Coroner

Coroner is a Swiss technical thrash metal band from Zurich, Switzerland. They garnered relatively little attention outside of Europe. Coroner's music combines elements of thrash, progressive rock, jazz, and industrial metal with suitably gruff vocals. With their increasingly complex style of progressive rock-infused thrash, they are often labeled as "the Rush of thrash metal" by music critics. Coroner's sound then progressed and the production became more refined, resulting in the more progressive No More Color, Mental Vortex and Grin albums.
