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. 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.

They 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.

The band stepped away in 1996 - but when they came back in 2011, it wasn’t to rehash the past. They had unfinished business. Edelmann bowed out after the early reunion shows, and longtime live partner Diego Rapacchietti stepped behind the kit, reigniting the band’s rhythmic core. Now, in October 2025, Coroner will release their first new studio album in over thirty years. This one took time. It moved slow, stayed quiet, and took shape mostly in the background. Until the moment felt right to let it surface.
