OBEISANCE (USA)

Based on "Lucifer Master": this band is a kind of a side project for the members of the Mexican death metal maestros The Chasm. The music, however, bears no resemblances to death metal, opting for classic thrash metal mixing some heavy, stomping riffing ala Celtic Frost with some faster, energetic numbers in the tradition of early Bathory and the Swedes Bewitched. This is straight stuff, you won't find any twisted, technical riffs typical for the The Chasm-style, but is very enjoyable and a very good reminder of the heydays of thrash.

OBLITERATION (UK)

One of the less known bands from the British metal scene. It's hard to define their style with a few simple words, though: there are fast, aggressive numbers; there are slower, doomy parts; there are mid-paced, semi-technical tracks, too. It might sound impressive to some, but as a matter of fact this is just an average thrash metal album.

Obscured Within Full-length, 1990

OBLITERATOR (USA)

This band was formed by Ski- the man who sang for Deadly Blessing previously, and the same man who was very close to becoming the Rob Halford replacement in Judas Priest (outrun in the last stage by Tim "Ripper" Owens). This could have been the beginning of a stellar career, if released 5-6 years earlier; the style is characterized by the typical for Deadly Blessing speed/thrash anthems, but the music is more technical and heavier (check out "Bloodred Sin"), and Ski screams his lungs out to the very extreme, seldom achieved before, even by Halford himself (check out "Bloodred Sin" again). Hey, there are other songs here, too, like the brilliant opener "Windows To Your Soul": another great brutal technical thrasher, as well as the Ski's tribute to Judas Priest- the cover version of "Beyond The Realms Of Death" with the vocal performance, of course, being the highlight.

Demo Demo, 1992

OBLIVEON (CANADA)

This great band never got the recognition they deserved. They play a unique brand of technical/progressive thrash with a certain industrial flavour on later works, heavy and mid-paced most of the time, with meaty, crushing riffs. Their debut fits this description almost completely, but it lacks the industrial decorations of the other albums, but is a first class slab of technical thrash. It opens with the excellent speedy, lead-driven instrumental "Access To The Acropolis", after which things take a heavier, and more technical turn, with "Chronocraze", which still enjoys a great faster-paced section. "Droidomized" increases the heavines, but without losing the speed, and the result is a fine intense thrasher, with a technical twist. The technicality remains for the great 9-min progressive thrash opus "Fiction Of Veracity"- one of the band's finest hours, a smashing combination of moods and tempo changes. "From This Day Forward" is a dark brooding mid-paced thrasher, with creepy, sinister guitars. "Imminent Regenerator" is technical speed/thrash at its smashing best, whereas the closing "It Should Have Stayed Unreal" slows down again, acquiring a dark, gothis edge.
"Nemesis" is the band's magnum opus, the finest example of their unique style, which also manages to stay away from the modern/industrial influences for most of the time. It starts in a fabulous way, with the technical masterpiece "Dynamo", with superb guitar performance. "Estranging Abduction" follows the same pattern, but "Factory Of Delusions" speeds up, and gets more aggressive, creating some headbanging atmosphere, which gets lost for the complex whirlwind of technical riffage "Frosted Avowals", which fans of progressive/technical thrash might find the highlight here. "Nemesis" relies more on heavy, crushing guitars, and is a nice pause, before another technical gem overwhelms you: "Obscure Mindways", this time faster, combining the best from Helstar and Despair in their prime. "Strays Of The Soul" shows the more lyrical, semi-balladic side of the band for a while, before the smashing technical riffs take over. "The Thinker's Lair" closes this incredible album with a mid-paced, more standard approach.
"Cybervoid" is a much more modern, and more immediate effort. There is groove, there is also industrial, but the interesting arrangements and the original musical decisions are still present, to a certain extent: "Perihelion", "Sequels". Still they are not enough to make this album sound even half as good as the first two ones; the apporach is too samey, making the whole album sound like one big track. The EP and "Carnivore Mothermouth" concentrate on the industrial and modern tendencies, leaving the technical flair far behind.

OBLIVION (ITALY)

A very obscure release, Oblivion's only mini-album is an enjoyable mixture of power and melodic thrash, with a nice finishing touch ("Pipes And Drums", which somekind of reminds me of ABBA's "Arrival"). Before this finishing touch, however, one will come across a very good fusion of power, speed and thrash metal: "Screaming Hearts", partially ruined by the emotionless, semi-clean vocals; one full-blooded intense thrasher: "Guilty Youth", with a great bass-bottom (which is very strong on the whole album, by the way); one feelgood crossover piece: "Let Leave Me Be Myself", and more.

Oblivion Full-length, 1990

OBLIVION (USA)

A very obscure band. Their only album mixes classic heavy metal ala Accept with some power/thrash in the Heretic-vein, or the later Ultimatum works. There are some punk-ish moments, too- "Get A Life", and as a whole the album doesn't have a very big headbanging potential, except for the live track "Cross The Line", which is a cool nod to the 80's American scene, and the galloping power/thrasher "Euthanasia", which loses in the process from the buzzy guitars.

Oblivion Full-Length,1989

OBSCENE GESTURE (USA)

A band formed by two ex-members of the mighty Agent Steel (Chuck Profus and George Robb). The style is not splashing speed/thrash along the lines of that legendary band, but (based on the demo) is quite a worthy slab of 80's thrash metal spiced with some crossover, reminiscent of Nuclear Assault and Sonick Plague. The full-length is an improvement in every department, not a very distant departure from the music displayed on the demo, but much more aggressive. The songs are short explosions of rage and fury, this time closer to Slayer's "Reign in Blood", or Sick Of It All, on the more hardcore-ish sections. Some more laidback, jolly numbers are certainly added (the album is 21 songs long): "Crumbs", "Lovely", but songs like "Warning" compensate for them with their brutal, grind-core approach.

OBSCURE (SPAIN)

Based on the "Curse the Course" demo, this is great thrash/death of the dark, but intense type reminiscent of Pestilence's "Testimony of the Ancients" and Infernal Majesty's "None Shall Defy". The tempo is frequently fast, but never too brutal, and the riffs are technical, but not as overtly technical as the ones on the Pestilence album, for example. The guitar hooks are very catchy and memorable, and are contrasting to the drastic, brutal death metal vocals. The only flaw is the unnecessarily long orchestral intro "Yellow Brick Road to the Void", which lasts for more than 3-min, and might stretch your nerves a bit.

OBSCURITY (SWEDEN)

One of the first bands in Sweden who explored the more extreme and "darker" corners of metal. Their style is a furious mix of black and thrash (some proto-death moments, too) metal akin to Possessed, Bathory and early Slayer.

OBSESSOS (BRAZIL)

A 4-song demo of really brutal thrash/proto-death, sounding well more vicious than their more renowned compatriots. Some tracks are pure death metal: "Satans Procreation", one of the earliest attempts at the style. The sound quality is very bad, with buzzy guitars, and low, gruff vocals, which do their best to sound as brutal and vicious as possible. This is the reason, I guess, why this demo sank without a trace, although from a poineering point of view it definitely deserves a mention when talking about the spawning stages of the death metal genre.

666 - The Ultimate Demo, 1987

OBSKUR (CANADA)

Quite good classic, mid-paced heavy thrash infused with some more melodic guitar lines, more typical for traditional heavy metal, but they don't sound awkward, and give the music a more catchy edge. There are some up-tempo moments ("Season of Witch", "Intru-mental", both great stomping thrashers with great leads and riffs), but they are compensated by pure hard'h heavy numbers ("Negligence").

Obskur Full-length, 1994

OCCULT (HOLLAND)

A black/thrash metal band. Their debut is mostly furious black metal with some slight hints of thrash. On "The Enemy Within" the transition is more than obvious: this is heads-down thrash with a strong presence of black metal. The next effort introduced death metal in the proceedings, but the black metal influences by then have been almost completely gone; this is a great album from where the band's best period begins. The following two albums are old school thrash at its finest, placing the band on the top of the thrash metal wave in Holland and worldwide. A change of name followed - from Occult to Legion Of The Damned, but the style pretty much remains the same, with a slight return of some of the black metal tendencies of old.

OCCULT (USA)

Based on the demo: two songs of raw early speed/thrash ala Hallows Eve and Razor, with a certain shade of hardcore on the short "Slaughterhouse", which also boasts the better guitar work, with a nice melodic main theme.

Agathocles/Occult Split, 2007

ODDECH BUNTOWNIKA (POLAND)

A 2-song demo of heavy, black-ish thrash obviously influenced by early Venom. The music is not very intense, and the vocals are a bit of an acquired taste, being shouted black-ish ones.

Już Tu Nie Wrócisz Szatanie Demo, 1987

ODDMONGERS (FRANCE)

Based on "The New Prometheus", this is modern 90's thrash metal, but these guys don't fall too often into the groovy "traps" set by Pantera, Machine Head and the likes; they opt for a more original, alternative sound reminiscent of Tool perhaps at times, but more aggressive and less adventurous. The clean vocals used on this album are quite good, but they would probably be more suitable for a doom or gothic metal act. This is cool, but melodic stuff, and might not satisfy the more hard-boiled fans.

ODIOUS (GERMANY)

Modern groovy 90's thrash, with a pinch of death and gothic; this is not headbanging stuff, as the music is mid-paced at best, with several quiet atmospheric moments.

Fallen Apart EP, 1995

OF RYTES (GERMANY)

The band where Mem Von Stein (Exumer) stopped for a while before his departure for the USA. "Without..." is by far one of the undisputable masterpieces of the whole German metal scene. Don't expect to hear any speed anthems like the ones featured on the Exumer's debut; this is very moody, mid-paced technical/progressive thrash which has no precedent on the scene. Von Stein lowers his vocals down to suit the music, and does a marvellous job as such. The style bears resemblances to the surreal atmosphere of Voivod's "Killing Technology", but surpasses it in musicianship on the best moments. It's hard to accurately describe such a great album. This is probably the first work to start the wave of progressive/technical thrash metal acts which appeared on the German metal scene in the early to mid-90's.

Without... Full-length, 1991

OFFENSIVE (JAPAN)

This is modern, groovy thrash/death metal which will remind you of the last two Massacra albums. The music doesn't sound stale, though, as the guys vary things from heavy, almost doom-laden numbers to some cool faster thrashers.

Existence Full-length, 2002

OIL (USA)

This band was formed by the ex-Dark Angel singer Ron Rinehart and the guitarist Blake Nelson. The style very slightly reminds of Dark Angel (some of the songs possess the heaviness of "Time Does Not Heal") being more modern, groovy with a certain doze of power metal, and Rinehart's vocals taking a more pleasant, melodic turn.

Refine Full-length, 2000

OLD (GERMANY)

One more band who are fascinated by Celric Frost and Hellhammer. The music is raw, slightly unpolished old school black/thrash along the lines of the aforementioned bands, with some more up-tempo sections ala Beherit and Barathrum.

OMEN (HUNGARY)

One cannot help, but notice that many of the Hungarian metal bands: Akela, Moby Dick, Fekete Sereg, Pokolgep, are a symbol of longevity and endurance. This band fit perfectly into this list, too. Omen were formed by two members of Pokolgep with the intention to play harder and heavier music than the other band. Well, they partially succeeded, especially on the first three albums where one could hear some nice thrashing along the more standard speed/power metal sections. The band's music has apparently missed its age, being clear classic power/speed/thrash, and although their later works adopt a more modern sound, they never completely betray their 80's roots.

OMEN (USA)

This legendary American power metal band's sole flirtation with thrash has the typical modern sound for its time, with groove and angry vocals, but is not that bad, with catchy songs and heavy riffs, universally denounced by the Omen fans. It begins quite well, with the heavy, aggressive opener in the Pantera-vein "Chained", but the rest is slower, less angry, and openly groovy, clinging towards Metallica's Black Album on the better moments.

OMENOMEJODAS (SPAIN)

Cool retro thrash sounding like many other bands from the 80's. The tempo is energetic, and the guitar work is quite good, albeit simplistic and direct. The singer is not really an asset, with his hoarse, hardcore-ish voice. There are some cool touches present, like the short folk-ish instrumental ala Skyclad "Imber", or the also short hardcore outburst "R.I.P.". There is some shade of hardcore on other tracks as well ("Enajenación Mental"). "Thrash Metal" is a truly aggressive piece of thrash, richly deserving its title. Its aggression is partially compensated by the jolly, light-spirited closer "Omenomejodas".

OMISSION (SPAIN)

"Day Of Your Death Arrives" is black-ish thrash with 80's spirit similar to Alastor from Portugal. "Yells That Destroys": after the imposing intro taken from "Star Wars", we are met with another slab of black/thrash, not a very distant departure from the debut demo, but with a better musicianship, leading to some really cool intense speed/black/thrashers: "Legions of Youth". The only pullback would perhaps be the brutal blast beat-based, black-ish track "The Light in My Dark". "Shadow on the Wall" is a nice heavy/power metal hymn.

OMNITRON (SWEDEN)

This is the band known as The Krixhjälters previously. Unfortunately, with the band's old name a certain part of these guys' talent must have gone, too, because the music is not even half as good. It retains some of the crossover elements, but it mixes it with some heavy-handed semi-technical thrash which leads nowhere. At times the sound acquires a very eclectic nature, aiming at the progressive metal realm, and these moments would be to the liking of those who enjoy albums like Voivod's "Dimension Hatross" and "Nothingface", but this is inferior. The album opener: "The Power Line", starts with some good riffs, but soon introduces the offbeat elements which take over the few more aggressive guitars scattered throughout. The only other place where you can find yourself headbanging, is "Torque Limit", but again for a while, where there is even an attempt at singing in Russian. Of course, there are songs where thrash metal is nowhere to be heard: "I Am He", "Five in Four". It's no wonder that the band disappeared without a trace soon after this only effort.

ONE MAN ARMY AND THE UNDEAD QUARTET (SWEDEN)

Apart from the long and pompous title, this band have something more to offer. This is actually Johan Lindstrand's (The Crown) new band. The style is also modern thrash, but unlike The Crown, it's mostly mid-paced with good, heavy riffs; one of the better bands from this over-saturated sub-genre.

ONSLAUGHT (UK)

An essential British thrash metal band. "Power from Hell" is a cool, raw debut, sounding like a more aggressive version of early Venom; apart from the up-tempo thrashy tracks, the band try something more melodic, in the form of the long mid-paced power/thrasher "Lord of Evil". The song "Death Metal" is far from the early attempts in the death metal genre, despite its title: it's actually a light speed metal number ala Motorhead; the next one is a much better effort: "Angel of Death": an intense speed/thrasher, almost touching the Slayer track of the same title. Later on there is at least one more energetic piece: "Steel Meets Steel", but the majority is not really striking, showing a band, still a long way from the better examples of the genre.
"The Force" saw the guys full equipped to compete with the best: with tighter and better musicianship each of the 7 songs is a heavy, thrashy tour de force, great combinations of heavy, pounding riffs and smashing faster ones. Shades of their more melodic debut album could be found in a heavy/power metal hymn like "Metal Forces", but the rest is uncompromising thrash with a unique dark atmosphere, recalling another very good act from the UK: Deathwish. The tracks are long-ish, within the 6-8min sector, but to talk about something more technical would be too far-fetched.
The band took a very premature decision to adopt a more commercial, accessible sound on "In Search Of Sanity" after which their fans abandoned them in draws. It wasn't completely bad, as a matter of fact; there were quite a few energetic thrashers present, and if we exclude the annoying overlong noisy intro, and the not very convincing cover of AC/DC's "Let There Be Rock", the rest was pretty decent, surrounded by the melodic, but cool soaring vocals of Steve Grimmett (Grim Reaper). "Welcome To Dying" is one of the band's best songs, albeit a bit long. Not happy with the acceptance, the band folded soon after this release.
On their comeback album the guys took a step similar to Exodus: they added a more modern sound to their basic old school approach, and it was the right thing to do, because "Killing Peace" is a real winner. The album starts with no mercy, with the great headbanger "Burn", but later on the groovy, modern trends spring up on several songs, occupying the middle; they might stretch your nerves a bit, but if you have a bit more patience, you'll reach the best, which comes in the form of another couple of nice retro thrashers ("Twisted Jesus", and especially the furious closer "Shock & Awe").

OPEN FIRE (POLAND)

Apart from Turbo and Wolf Spider there was another band who played some great thrash metal in Poland. How these guys remained so obscure, is a mystery... The band owe more to the speed metal heritage of Helloween and Warrant than to their compatriots. The album is full with great lead guitar work ala Kai Hansen and speedy melodies, topped by nice melodic soaring high vocals.

Lwy Ognia Full-length, 1988

OPHYDIAN (ITALY)

Modern power/thrash of the more melodic type, with slight alternative elements. The vocals are good, but are too melodic for the style, and the more peaceful moments are a bit overused, and consequently the ballad "Snake Eyes" appears to be the best song here.

OPPORTUNITY (THAILAND)

Modern thrash of the more melodic type, still having its edge ("Throne", "Fire") whenever necessary, but often relying on the groovy patterns as well ("Grudge", "Unleashed"). "Dog Nation" is quite a good combination of the two, and on top of that we have nice melodic lead guitars.

Based on "Zombified", these Singaporeans come up with a very enjoyable blend of energetic classic thrash metal and punk. Yes, punk-that's right! It will probably not appeal to punk fans too much, though, because the sharp, thrashy riffs dominate, but the inimitable punk spirit of the late 70's-early 80's is all over the album.

This band were formed after the split-up of Deadly Blessing by some members of that band.

Still the classic sound dominates, and what we have here is quite good power/thrash with excellent powerful vocals, and heavy riffs.

ORACLE (USA)

This band's short career crosses paths with Iced Earth as two of their members have played in the more renowned band. This is a very strong progressive power/thrash metal album which draws comparisons to Nevermore and Eidolon. The songs are long (some of them go over the 9-min range), but never sound boring even for a single second, with dark, almost gothic atmosphere and nice, crunchy, heavy riffs. The tempo is mid-paced, with a very few exceptions. The softer moments ("Paradise (on the edge of the world)"), which are not too many, will bring you back to the time of the Queensryche's debut mini-album. The man who steals the show here, is Kent Smedley- the guitarist, who is truly one of the finest to ever grace the metal scene, and one of the least known. His performance is simply amazing: melodic, fast, but at the same time very technical leads decorate every track, and although on the longer ones he's been given quite a room to display his talent, you will hardly complain, since his pyrotechnics are just breathtaking. It's too bad this man never recorded anything else; could have been a very valuable addition to the Shrapnel catalogue, and certainly one of its most prominent representatives. The other person worth mentioning, is William Wren- a great singer whose passionate powerful clean vocals will haunt you long after this album is over; he later joined the progressive power metallers Mystic Force.

ORCHRISTE (SWEDEN)

This band was founded by members of Seance who wanted to keep themselves busier, one of them Patrick Jensen: the guitarist who has also taken part in Witchery, The Haunted, Brujeria, and other acts. What we have here is 2 songs which stylistically are not too far from the Seance output, with a more thrashy edge. Maybe the guitar work is more technical, especially on the long dark thrasher "Blessing of Death". "Open Grave" is an aggressive, bashing thrash/death piece.

Necronomicon Demo, 1989

ORDAINED FATE (USA)

A cool female fronted, slightly progressive, power/thrash metal band. At times the music loses its edge and descends into classic heavy metal territory, but there are enough hard-hitting riffs to keep the thrash metal fan satisfied. The music alternates between more simplistic tracks, and more complex, technical ones. The singer has a cool, mid-ranged tember, coming as a mix between Doro Pesch and Leather Leone. The problem is that the tempo is too one-dimensional: mid to slow, with a few timid attempts at more energy ("The Election", which is actually the only full-blooded thrasher).

ORDRENEKT (NORWAY)

The Norwegian metal scene has been trying to show in the past few years that apart from black metal acts, it could also provide bands for other metal genres. Based on the full-length debut, Ordrenekt play thrash/crossover recalling quite a few veterans from the 80's; the songs are mostly energetic and up-tempo, but are longer (3-4 min) than what usually goes with this style, and with a decidedly more thrashy edge ("Anatomy Of Pain" is a nice example of the more thrashy nature of this band's music).

Quite a wild mixture of very heavy, modern groovy thrash, sludge/doom not too far from Eye Hate God and Acid Bath, some grind-core moments (but not too many), and a certain amount of hardcore. I'm not sure whether it would appeal to the regular thrash metal fan, but it's really worth hearing. The closest soundalike would probably be Lair Of The Minotaur, but these guys here care less about pure thrash metal.

ORGY OF FLIES (BRAZIL)

Based on the "Soul Resurrection" demo, Orlok are a melodic modern thrash metal band with a somewhat gothic edge reminding me of Rotting Christ's more sophisticated period ("Dead Poem", "Sleep Of The Angels") if we exclude, of course, the hardcore-tinged vocals. This is not sharp, edgy thrash, but is far from dull, with some tasteful melodic guitar riffs present.

OSAMENTA (ARGENTINA)

Fast, occasionally intense thrash metal reminiscent of Sepultura's "Beneath The Remains" on the more aggressive sections, well done. Despite the big number of the compositions (14), the band stretch at least half of them, beyond the 5-min range, "Osamenta" reaching 10-min, and is quite a diverse track in itself, easily going from short furious blast-beats to heavy doomy sections. "Heridas del Futuro" is not too far behind in terms of length (9.5-min), but is more consistent, without too may extremes, boasting some sparce, but cool Oriental tunes. The album is not constant bashing, on the contrary, it offers quite a few slower, atmospheric passages, as well as some attempts at more lyrical, balladic play ("Camino al Destino", where the sharp guitars are well intertwined with the piano background melody; "Lágrimas de Dolor"; the excellent short closing instrumental "Atardecida Soledad").

OSIRIS (HOLLAND)

Very complex progressive thrash recalling Watchtower at times. The music often hits the mark, but at the same time some parts sound unfocused as though being independent within the song-structures, unrelated to what has been before and what comes next. When the band keep things short, they really hit with power ("Mass Termination", "Inner Recession"), but apparently Osiris' aspirations were looking elsewhere. For fans of non-standard thrash this should be quite interesting.

OSMIUM (USA)

A very good mix of classic and modern thrash with good, sharp riffs, and heavy tracks in the mid-tempo, recalling early 90's Sepultura (a mixture of "Arise" and "Chaos AD"). Catchy short modern thrash hymns await you here ("Drifting Away", "The Last Good-Bye", which also comes served with a great retro thrash section in the middle), as well as more melodic, but quite effective numbers ("Jesus Lover").

OUT OF ORGER (GERMANY)

This is another very good power/thrash metal band of the old school. Out Of Order combine long, epic power songs with some fast, razor sharp thrashers. The style is close to contemporary Agent Steel and the Polish Hellfire. "Powered by Aggression" is the more melodic affair, with a bigger doze of power/speed metal elements and epic moments. The songs are longer and more complex, freshened by some shorter, more immediate thrash pieces ("Dead End"). Some of the longer numbers also try to keep speed and intensity the whole time- "Terror Rules", and succeed most of the time. "Back in Hell" is the more thrashy effort, boasting great sharp riffs, making even the slower, calmer numbers ("God of Misery", "Back in Hell") sound intense. The base of the album, however, is the speedy tracks, and they crush in a major way: "Seven", "Blue Eyed Tornado", etc. The songs are shorter, except for the album closer "Invisible Empire", which is a great speed/thrash metal opus, in the best tradition of the aforementioned bands.

OUT OF THE LAIR (GREECE)

Thrashy power metal similar to the Germans Brainstorm or Manticora from Denmark. There are some cheesy moments (in the choruses mostly), but there are, on the other hand, enough thrash breaks scattered throughout the album to satisfy the average thrash metal fan. Another minor complaint would be the vocals, which sound quite strained at times, especially when the guy goes for the high tones. Things would become really interesting if the band vote to concentrate for the future on their "dark", thrashy side.

OUTBREAK (CANADA)

One of the best kept secrets from the Canadian ungerground, Outbreak offer first rate power/thrash, which is obviously influenced by their more renowned compatriots Anvil, but these guys do a much better job. The opener "Master Stroke" is a great galloping power/thrasher in the vein of Omen, Attacker and, of course, Anvil. "Uberalles" carries in the same vein, but speeds up, and the guitars take a more aggressive, thrashy edge. "Hell on Earth" is a brilliant technical power/thrasher, with overwhelming haunting riffs and superb melodic leads; for this song alone this album is a must! "Mein Kampf" is an all-out thrasher, fast and merciless. Then comes the odd hard'n heavy number "Love", something which sounds as though directly taken from the Anvil debut. This lyrical, romantic song is followed by another awesome galloping thrasher: "Spy Killer", again graced by some fascinating guitar work. "Leader", with its leaden, super heavy riffs strangely reminds me of the Candlemass' attempt at thrash "Cry from the Crypt". "Triumph" is a really triumphant end to this masterpiece: a great up-tempo thrasher, with a very memorable, headbanging main riff. The singer is an acquired taste, though; high-pitched, screamy, but kind of fitting to the music. This album is one of the mandatory works of metal; you can give it a listen on the link provided below.

OUTBURST (FRANCE)

The word "thrash" is frequently present on the band's works' titles. Based on the "Pure Thrash" demo, this is really pure old school aggressive thrash metal in the Slayer and Vio-lence vein.

OUTBURST (HOLLAND)

One of the better modern thrash metal bands; perhaps this is because their music has something from the classic school, too. The band waste no time, starting with the intense headbanging instrumental "220", which is pure retro thrash delight, thrashing intensely for a little more than 2-min. The modern sounds come with the next "Freddy's Song", along with some more melodic than the main ones vocals, mixed more brutal, death-ish ones. The classic thrash tunes come back for another furious piece: "The Beast Will Strike Again", followed by the more technical exercise "What The Eyes See", which is a great thrasher, with a slight twist. "Slaughterhouse" is a more ambitious track, longer and more elaborate, but fails to deliver the goods in a way the others did. So the guys are quick to bring back the more successful, simplistic intense thrash formula, with "The End" and "My Own Hell". "Attack Of The Overfiend" is an awesome mix of speed, thrash and a bit of death metal, a larger-than-life opus (not very long: 6-min), with great melodies and crushing riffs.

OUTCAST (FRANCE)

Excellent aggressive classic thrash reminiscent of Slayer’s “Reign in Blood”, Devastation’s “Idolatry”, Atomica’s “Disturbing the Noise”, etc. There are some death metal blasts thrown in for good measure, and as a whole the music is really fast and relentless, except for the odd acoustic, ambient instrumental “Deus Ex Machina” serving as an intermission, and a short break before the next assault. The leads are superb, but the riffs are not far behind, hitting hard, leaving marks all over you (a joke!). “The Same Face From Passion To Hatred” is a magnificent technical thrasher, the only one of the kind on this album (sections from “ To What I Belong” sound too technical, too), with great twisted riffs in the Coroner vein, quite brutal as well near the end: surely the highlight, and hopefully more of the same will be heard on the band’s next efforts. This is one of the most impressive releases to come from France for quite some time, and a sure top ten pick for the thrash fan for 2005.

OUTRAGE (AUSTRALIA)

A very good demo of mid to up-tempo classic thrash in the Anthrax vein, with nice riffs, not very hard-hitting, but anjoyable: three of the songs. The last one: "Fear No Fear", is a marvellous turn to technical/progressive thrash (could be written at a different stage of the band's career?), resulting in a feast of smashing technical riffs and tempo changes, closing on slightly over 9-min.

Songs For A Romantic Evening Demo, 1991

OUTRAGE (CANADA)

Based on the "Outrage" demo, these guys pull out several styles, all of them in a fairly good fashion: "Cabalistic Rites" is a fast, aggressive track with a certain proto-death flavour; "Horror Night" is a cool, more restrained speed/thrasher; "The Terminator" is clearly the highlight here, featuring a fine combination of slower, almost doomy riffs and some very fast ones, topped up by a few nice technical licks; "The Rapist" is another excellent aggressive thrasher. With 5 demos released within a relatively short period of time, it was clear that the band wanted to make an impact on the scene, and judging by the talent displayed on this demo, they definitely deserved to be better known.

OUTRAGE (GERMANY)

Unfortunately, from this impressive discography, I am only in the possession of the first demo, based on which these guys were surely one of the most extreme acts on the European metal scene in the mid-80's. This is a brutal mix of black and thrash, with nods to early Celtic frost and Hellhammer ("Go to Hell"), and Burzum (the monotonous and vicious "Death from Behind"). There is not much variety in the guitar approach, but this creates a somewhat hypnotic effect which might be appealing to some, and was later used by many, mostly black metal acts: Beherit, Barathrum, Khold, late period Satyricon, Mayhem, etc.

OUTRAGE (ITALY)

This band are probably the first speed/thrash metal band in Italy. The music is fast and recalls both Agent Steel, and the speedy heroes from Germany Iron Angel and Warrant. Another Italian band- Creepin' Death, might have been influenced by this band. The second demo comes with a better sound and some nice deviations from the speed pattern in the form of abstract, semi-technical thrash strangely reminding of Voivod's same year's "Killing Technology": "Acid Brain". Unfortunately, the band's big potential was never fully realised.

OUTRAGE (JAPAN)

One of the longest running, and best Japanese metal bands. "Black Clouds" is a good speed/thrash debut with a clear Metallica influence. "Curtains of History" is not a very convincing opener, hesitating between a more technical and more accessible, faster style. The technical style "wins the battle", as the other songs become longer, increasing the complexity; the problem is that the guitar sound is very thin and abrasive, and irritating; the other flaw is the semi-hardcore, hoarse vocals which are anything but suitable to the much better music.
"Blind To Reality" is excellent heavy technical thrash, with long, but interesting tracks, along the lines of Metallica's "Master Of Puppets" and "...And Justice For All". It's not a very distant departure from the debut, but the guitars are much better heard, sharper and heavier; it begins with the good headbanger "Blind to Reality", but later the music takes a more technical approach, and the speed decreases, springing up here and there ("Name Your Poison"). The guys perhaps overdo it on the last song- the 11-min "Lockin' At Time", which is nothing more than a veeery long, and boring ballad, which tries to "apologize" for the wasted time with a cool speedy outro, but it would rather serve to wake the listener up.
"The Great Blue" is a transitional album showing the band gradually acquiring the modern elements: the songs have become shorter and more light-hearted, but the staple razor sharp riffs guarantee another thrash entertainment. It's actually a fairly satisfying listen, keeping good speed for most of the time, although the abrasive guitar sound of the debut kind of comes back. Cool headbangers like "Days of Rage" and "The Truth" stir the mood in a major way, and even more melodic experimental numbers, like "Clay Liner", sound appealing. The pullback is again, in the form of a ballad, again quite long and dragging (9-min this time, thank god!), although the lead guitar work at least this time is cool. The future works of the band feature modern, groovy thrash which also have their interesting moments, but you have to listen with care in order to hear them.

OVER FAITH (ITALY)

A very good demo of classic 80's thrash with some slight death metal-overtones. The tracks are long-ish (within the 5-7min range with one epic massive 9-min track- "Fear (Darkness Embrace)"). Apart from the aforementioned track, the rest is cool speedy music offering some nice headbangers- "Madness Stole My Life" is perhaps the finest representative of the latter.

OVER US EDEN (GERMANY)

A standout progressive power/thrash metal band with the former Living Death drummer Rainer Schmitz on board, and a female singer whose voice resembles the legendary Doro Pesch from Warlock. The style is not far removed from the bands of the progressive thrash wave characteristic of the German metal scene during the early-mid 90's, and more particularly Depressive Age and Lost Century. Over Us Eden are maybe less adventurous with a thicker, heavier sound which at times recalls Nevermore.

OVERCAST (GREECE)

Along with Crucifier and Released Anger, this band are doing a very good job to establish the Greek thrash metal scene as one of the best in Europe nowadays. The guys' music is a very potent mix of Tankard and some Bay Area riffage (think early Testament). The singer doesn't hide his fascination with the Andreas "Gerre" Geremia (Tankard) vocals, but they fit the music just fine. Some cool Oriental touches could be heard on the smashing album opener "Middle East Terrorist", as well as death metal blast beats on "Angels in Fire". The tempo is quite fast and intense, with nice slower, crushing breaks.

OVERDOSE (BRAZIL)

Overdose are one of the first Brazilian metal bands, having started at the same time with Sepultura, but having failed to achieve the same level of success and popularity. The band's style is less aggressive than the one of their renowned compatriots, with their earlier works being more power metal-based, and their later ones opting for a modern, groovy sound. The album which deserves attention on a site like this is "Circus Of Death"- the band's most thrashy release. The opening track- "Violence", starts the album in a very aggressive way, but the rest is mostly in the mid-paced department, and the band's power-metal roots could clearly be heard on many of the songs. As a whole, this album can be rightfully put among the better power/thrash metal efforts of the Brazilian metal scene of the 90's. On later works the band embraced the modern groovy metal idea tight, also adding some industrial overtones on "Scars" in a way similar to Prong's "Rude Awakening".

OVERDOSE (FRANCE)

Despite the bad sound quality, one could recognize some decent power/thrash metal close to their compatriots Killers. The guys try to reach more progressive metal waters, with longer numbers like "Cendres de Liberté", but the simplistic, one-dimensional delivery would make the listener tired quickly. Hard'n heavy numbers like "Princesse De l'Enfer", do not make things any better. The second half (the demo is 8 songs long) is the better one, with the heavy power/thrasher "Condámne A Mort", and the melodic, but cool instrumental "Légende".

Chasse ŕ l'Homme Demo, 1988

OVERKILL (USA)

This seminal band started greatly, with "Feel the Fire", which remains one of the highest achievement of the 80's American power metal scene. "Taking Over" hardened the course a bit, but was still in the speed/power metal field. The movement to thrash was finally completed on "Under the Influence", which featured some forceful sharp riffs, slightly recalling their colleagues from Anthrax. "The Years of Decay" saw the band moving away from all influences, and forging their unique, heavy sound, on this one expressed by longer, more complex song-structures, with a healthy pinch of doom (check out the monstrous, 10-min "Playing With Spiders / Skullkrusher"). The improvement in every aspect inevitably led to the band's crowning achievement: the incredible "Horrorscope", which was one of the last great works of thrash, before the genre's sunset.
Then it was time for some modern thrash, and the guys wasted no time picking the modern tendencies, well displayed on "I Hear Black", which was quite a step down from the band's last couple of albums, flirting with no fear with all the gimmicks of the 90's. Then "W.F.O." came crushing, with some awesome riffs from the past, showing the guys not completely willing to bid farewell to the 80's. But after that followed a string of modern thrash efforts, which weren't so bad, including an all cover-album ("Coverkill"). "Killbox 13" was a good return to form, containing the band's strongest material in quite a while, but instead of continuing in the same vein, especially when the time was just perfect for some retro thrash, they came back to the safer groovy formula, with "ReliXIV".
"Immortalis" is a mixed bag, with half of the songs recalling the band's heydays, and the other half staying closer to their more modern sound.

OVERLOAD (CROATIA)

Melodic power/thrash is on offer here, coming with great melodic lead guitars; will not be first choice for the average thrash fan. The sound quality is too muddy for one to appreciate fully this stuff, but energetic tracks like "Sumrak" and "Kroz Noc" are too good to be completely buried without a trace in it.

OVERTHROW (CANADA)

Excellent fast, aggressive thrash metal with some good technical riffs. Early Sadus would be a good reference point, or perhaps Gammacide. The songs come together as one big relentless attack on your ears, and although you won't be able to remember much from the album later, the pure aggression of it will make you go back to it over and over again.

OXIDATION (USA)

A blend of classic thrash, mostly heavy and mid-paced slightly resembling Cerebral Fix, but with a more modern, somewhat mechanical sound. The vocals are a problem, though, being very screamy at times, with awful shouts, which should be avoided for the future if the band want to make a bigger impact on the scene. The lead guitar work is quite good, but somehow doesn't fit the otherwise not very impressive music.
