Jean-Yves Thériault is a composer, producer, sound engineer and a musician. He is an accomplished bass guitar player and has created several scores for contemporary dance.

Thériault began his professional musical career in 1982 at the age of twenty in Jonquière, Québec. A co-founder with Denis D'Amour (guitar) he played the bass for VOIVOD, he toured internationally from 1982 to 1991. He is known in the metal world for playing with ferocious attack and for his trademark distortion - . His signature bass guitars were designed by him with the colaboration of Mauro Liberatore, a four string and a five-string high B. Thériault wanted to play chords which would make the bass sound more like a guitar but bigger.

He composed and recorded six albums on Mechanic/MCA(USA), Noise International (Germany), Metal Blade (USA) with guitarist Denis "Piggy" D'Amour, singer Denis "Snake" Belanger and drummer Michel "Away" Langevin. Voivod were exploring the concepts of Cyberpunk and state-of-the-art artificial intelligence long before these ideas were assimilated into popular culture.

A co-founder of The Holy Body Tattoo Dance Society, along with choreographers/performers Noam Gagnon and Dana Gingras, from 1992 to 1999 Thériault composed intensely resonant and evocative musical landscapes that left an indelible impression on the contemporary dance world. Through the use of electronic sampling, sequencing and programming, he produced and engineered the full length scores for "White Riot", "Poetry & Apocalypse" (co-composed with Craig Riddock) and "our brief eternity". He toured North America and Europe from 1996 to 1998 as both a sound engineer and a musician. Thériault was awarded 'Best Use of Sound/Music' in 1988 from the Canadian International Annual Film/Video Festival for the film version of "Poetry & Apocalypse".

In 1997 Thériault recorded the "The Electronic Voice Phenomena" CD with Mark Spybey, which was composed using sequencers, samplers, analog keyboards and various sound modules and devices. He continued to create experimental recordings in collaboration with Australian artist Matt Warren. In 2006 they created sound for the performance installation "BUG" presented at CESTA's (Tabor, CZ) 11th Arts Festival in 2006. In February 2008 they presented a piece titled "Hiatus" at Inflight Gallery in Hobart, Tasmania.

In 2006 Thériault co-produced NEGATIVA's self-titled 3 song EP with Pierre Rémillard. He rejoined Voivod between 2008 and 2014. He wrote most of the music for an other Voivod album title Target Earth which was release in 2013 on Century Media (USA). "I now regret having wrote that album and reforming the band simply because Voivod was initially Piggy and I idea and without him the band was over. Voivod started because of Piggy and should have ended after his death."

Thériault has engineered sound for rock acts such as extreme metal band GORGUTS, NEURAXIS, DECAPITATED and many others. He performed in 2002 with the metal "supergroup" BLACK CLOUD, featuring Pierre Rémillard (OBLIVEON) on guitar, Florent Mounier (CRYPTOPSY) on drums, and Patrick Mireault (GHOULUNATICS) and Marc Vaillancourt (B.A.R.F.) trading off on vocals.

Thériault is currently working with Monica Emond on the artistic project call ' Coeur Atomique '. He finally feels that now the music that he is writing with Monica Emond is meaning something more than just writing Metal riff and it is 100% DIY. They have released their first album "Landscape of emergency I" available through their website, you can support them by purchaising various items at their website.
