Aggression was formed in the spring of 1985 in Laval, Quebec. They recorded the album “Forgotten Skeleton” in 1986 (which didn’t see release until 2004). The Full Treatment album came out in 1987 via Banzai Records. During this time the band regularly played with the likes of Voivod, Anvil, DBC, Sacrifice and Celtic Frost among others. The Thrash Metal band was quietly put to rest in 1989. Sasquatch got the band together for 2 shows for a 20 year reunion in 2005.
In 2014, now calling Vancouver, BC home, Sasquatch has enlisted help from vocalist Brian Langley (Infernal Majesty), and eventually bassist Jon Power (Over the Coals) guitarist Dave Watson (Entropia) and drummer Ryan Idris (ExPain) to breathe new life into Aggression. Since reforming, the band has been playing festivals and touring all over North America and Europe. They released an demo compilation with a few new studio tracks in 2015 (Fractured Psyche Demons) and their first full length album in close to 30 years (Fragmented Spirit Devils) in November 2016.
