Prong and Voivod

Prong is an American heavy metal band formed in 1986 by Bassist Mike Kirkland and guitarist Tommy Victor, the band's sole constant member. To date, they have released twelve studio albums (including an album of song covers), one live album, four EPs, one DVD and one remix album. Prong had two independent releases — Primitive Origins (1987) and Force Fed (1989) — which attracted the attention of Epic Records, who signed the band in 1989. Their first two albums on Epic — Beg to Differ (1990) and Prove You Wrong (1991) — were released to critical acclaim and garnered attention on MTV's Headbangers Ball. The band's 1994 album Cleansing was also very successful, and included one of their well-known songs "Snap Your Fingers, Snap Your Neck" Voivod (or Voïvod) is a Canadian heavy metal band from Jonquière, Quebec. The band's current line-up consists of Denis "Snake" Bélanger (vocals), Daniel "Chewy" Mongrain (guitar), Dominique "Rocky" Laroche (bass) and Michel "Away" Langevin (drums). Their musical style has changed several times since the band's origin in the early 1980s. Starting out as a speed metal band, Voivod have added a mix of progressive metal and thrash metal to create their own unique metal style, and they are credited as one of the "big four" Canadian thrash metal bands, along with Sacrifice, Razor, and Annihilator. Since 1982, when it was co-founded by guitarist Denis "Piggy" D'Amour, Voivod have released fourteen studio albums, as well as one EP, one live album, two compilations, seven demos and one DVD featuring a live concert.
