Canadian thrash metal band.
Founded in 1985 (originally under the moniker "Asylum") by guitarists Denis "Sasquatch" Barthe and Bernard "Burn" Caudron. The lineup was completed by Éric "Butcher" Langlois (vocals), Yves "Dug" Duguay (bass) and Gaëtan "Gate" Bourassa (drums).
Split up in 1989, the band reunited in 2005 for a few shows, but was put to rest again. In 2015 it was resurrected again.
