Jean-Yves Thériault

Jean-Yves Thériault (, born 15 December 1962) is a Canadian musician who was the bassist for thrash/progressive metal band Voivod. He co-founded the band and appeared on the first six albums – War and Pain, Rrröööaaarrr, Killing Technology, Dimension Hatross, Nothingface, and Angel Rat. He departed the group in 1991 for personal reasons, and went on to co-found The Holy Body Tattoo Dance Society from 1992 to 1999. He composed, produced and engineered the scores for "White Riot", "L'Orage", "Poetry & Apocalypse", and "Our Brief Eternity".

In 1997 he released The Electronic Voice Phenomena CD with Mark Spybey and established the X-voto Recording label.

Thériault co-produced the Negativa self-titled three-song EP with Pierre Rémillard at Wild Studio in St-Zenon, Quebec.

Thériault returned to Voivod in 2008, after releasing a statement on 26 August 2008 regarding his involvement with the band.

Thériault continues to create electroacoustic music. His collaboration Hiatus, created with Australian artist Matt Warren, was presented in conjunction with the photographic work of artists Lena Stuart and Sally Rees at the Richmond, Virginia, InLight Festival on 5 September 2008.

Thériault performed on Voivod's 2013 album Target Earth, also collaborating in composition. On 10 July 2014, it was announced that he had once again parted ways with Voivod.

Thériault is currently working with Monica Emond on a new artistic project called Coeur Atomique. The duo have since released two songs and video entitled, "Castle Bravo" "The Waste". Coeur Atomique first album was officially released on 10 July 2017. A second album titled Landscape of Emergency I was released through Coup Sur Coup Records in 2021.
