Jean-Yves Thériault

Voivod is a Canadian heavy metal band formed in Jonquière, Quebec in 1982. The original line-up consisted of vocalist Denis "Snake" Bélanger, guitarist Denis "Piggy" D'Amour, drummer Michel "Away" Langevin and bassist Jean-Yves "Blacky" Thériault. The band has had numerous members changes throughout its 44-year career, with Langevin as the only consistent member. As of 2014, the line-up includes Langevin, Bélanger, Daniel "Chewy" Mongrain (guitar) and Dominic "Rocky" Laroche (bass).

Voivod's musical style has changed numerous times since its inception. Starting out as a speed metal band, they have added a mix of progressive and thrash metal to create their own unique metal style, and have been credited as progenitors of the technical thrash metal sound along with Coroner, Watchtower, Dark Angel, Mekong Delta, Anacrusis and Blind Illusion, among others.

To date, Voivod has released sixteen studio albums, as well as one EP, one live album, two compilations, seven demos and one DVD featuring a live concert. They have been grouped with Sacrifice, Razor and Annihilator in the "Big Four" of Canadian thrash metal. The band found mainstream success in the late 1980s with their fifth studio album Nothingface (1989), which is Voivod's only album to enter the Billboard 200 charts, peaking at number 114. The band won the "Visionary" award at the 2017 Progressive Music Awards. In 2019, Voivod's fourteenth studio album, The Wake, won a Juno Award for Metal/Hard Music Album of the Year. Voivod's most recent studio album Morgöth Tales, a collection of re-recorded songs, was released in July 2023.
