Coroner

Coroner is a Swiss thrash metal band from Zürich, active from 1983 to 1996 and again from 2010 onward. To date, the band has released six studio albums: R.I.P. (1987), Punishment for Decadence (1988), No More Color (1989), Mental Vortex (1991), Grin (1993) and Dissonance Theory (2025).

Coroner's music has combined elements of thrash, classical music, avant-garde music, progressive rock, jazz, and later on in their career, industrial metal and groove metal, with suitably gruff vocals. With their increasingly complex style of progressive-infused thrash, they have been called "the Rush of thrash metal", and along with Voivod and Watchtower, the band has been credited for helping pioneer the subgenre of technical thrash metal during the mid-to-late 1980s. Coroner's sound then progressed and the production became more refined, resulting in a more progressive sound on later albums such as No More Color, Mental Vortex, Grin and Dissonance Theory, while the latter two also saw the band adopt characteristics of groove metal. Their early works had a strong influence on the death metal scene of the late 1980s/early 1990s, especially on the technical death metal subgenre.
