Formed in Zurich, Switzerland in 1983, Coroner were originally roadies for fellow Swiss avant garde thrashers, Celtic Frost. In fact, Frost frontman Tom G Warrior sang vocals on the bands demo, Death Cult. Signing to Germany's Noise Records in 1987 the band produced five albums for the label over the next nine years – R.I.P. (1987), Punishment For Decadence (1988), No More Colour (1989), Mental Vortex (1991) and Grin (1993).
Starting out from the 80's thrash scene the band's sound soon progressed to encompass elements of classical, avant-garde, prog, jazz and industrial and their increasingly complex style of progressive rock-infused thrash garnered them the nickname, "the Rush of thrash metal." After a 16-year-hiatus, Coroner reunited to play a handful of highly anticipated live shows in 2011. In 2016, the band followed their live-comeback with the Autopsy documentary/live/best-of release and announced plans to issue a new studio album, 25 long years after their last studio album (Grin).
Grin, Coroner's fifth and final album for Noise Records, saw the band move even further forward with sonic diversity and encapsulated a more groove lead sound with industrial elements, which became popular during the mid-nineties. It's songs were longer, more complex and the most experimental the band had ever written. Grin is a technical marvel and in the early-90s was risky and very ahead of its time which has led to it being hailed, posthumously as an innovative classic of its genre.
