Coroner kicked things off in Zürich back in 1985 and quickly built a reputation as one of underground metal’s most forward- thinking and technically ferocious bands. With Ron Broder on bass and vocals, Tommy Vetterli on guitar, and Marky Edelmann on drums, the trio put out five critically praised records and a semi-compilation between 1987 and 1994, each one dragging thrash metal further into innovative, more experimental territory.

Coroner’s sound has always lived at the edges. It’s a collision of speed, structure, and control. Built on thrash, their music pulled in classical form, avant-garde twists, jazz complexity, and the cold mechanics of industrial metal. Every piece was delivered with pinpoint precision and Ron Broder’s unmistakable vocal grit. Often called “the Rush of thrash metal,” Coroner, along with bands like Voivod and Watchtower, helped shape what would later be known as technical and progressive thrash.
