oivod started off with Denis Belanger (vocals), Denis D'Amour (guitar), Jean-Yves Theriault (bass) and Michael Langevin (drums). They didn't waste any time getting started for their debut album, War And Pain (1984), was very unconventional and avant-garde at times, but it was well received by the music consuming public, making them one of the first Thrash acts to make a name for themselves internationally. Their second album, RRROOOAAARRR (1986), followed much in the same style and featured a name to match; its noisy neo-Industrial style made them popular in the underground Metal scene. Killing Technology (1987) showed improved musicianship and advanced lyrical content.
Dimension Hatross (1988) was the release that brought this act into their own and made them pioneers in the genre. Now the basic Thrash attack was merely a backdrop to the Progressive overtones and, although it perplexed reviewers, they still didn't hesitate to offer much deserved praise.
Nothingface (1989) saw the Thrash style shed almost completely. The album was a phenomenal success helped, in big part, by the remake of Pink Floyd's Astronomy Domine. Theriault would now leave, to be replaced by Pierre St-Jean for the release of Angel Rat (1991), their only release for major label 'MCA'. The follow-up, Outer Limits (1993), although receiving less notoriety in the press, nonetheless continued to demonstrate their staying power in the industry by successfully changing from one genre to another and keeping a fan base across the Metal spectrum. This album saw the inclusion of Eric Forrest handling both the vocals and bass duties. His inclusion in the band, however, changed their sound again and by the aptly titled Outer Limits the change was in full force.
Now they were drifting back, albeit gently, into their original style of harder Thrash. With Negatron (1995) they switched to the indie 'Mausoleum' label, but by Phobos (1997) and Kronik (1998) they were with the Canadian indie 'Hypnotic'. It would be 'Century Media', however, that picked them up for the live disc Voivod Live (2000).
There was a long pause whereby the band had broken up after Forrest's departure but an 11th hour decision gave them life again when Jason Newstead (ex-Metallica/ex-Flotsam And Jetsam) stepped in as a session bassist to eventually become permanent, and Denis Belanger (a.k.a. Snake) returned for vocal duties on their self titled 2003 release that showed them revisiting their past roots.
