Biography

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.
The albums they released on Noise Records didn’t just push the genre’s limits. They dismantled them
and put something sharper in their place. Even now, those albums are considered cult staples. You
could say they laid the groundwork for what progressive metal became:

A work born from silence, friction, and control.

R.I.P. (1987)

Punishment for Decadence (1988)

No More Color (1989)

Mental Vortex (1991)

Grin (1993)

Coroner (1994 | self-titled semi-compilation)
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.
With each release, their sound pushed further. By the time No More Color, Mental Vortex, and Grin
hit, things had grown sharper. The production became tighter, the arrangements more offbeat, and
the sound had drifted far outside any genre map.
That influence stuck around. From major players in metal to offbeat experimental types, generations
have taken something from their no-rules, no-compromise approach. For a lot of people, Coroner
weren’t just ahead of their time. They were the reason to start thinking differently about what metal
could even be.
The band stepped away in 1996 and disappeared from the spotlight. But when they came back in
2011, it wasn’t to rehash the past. They had unfinished business.
Marky Edelmann bowed out after the early reunion shows, and longtime live partner Diego
Rapacchietti stepped behind the kit, reigniting the band’s rhythmic core.
Since then, they’ve played select shows and festivals across the globe — Hellfest, Maryland
Deathfest, Brutal Assault — and headed back to the U.S. in spring 2025. More European dates are
lined up for summer. Every show brings the weight of where they’ve been and the tension of where
they are now.
After more than three decades, Swiss pioneering technical Metallers Coroner return with a new studio album: “Dissonance Theory” will be released on October 17^th, 2025 worldwide via Century Media Records.

To kick off the campaign for Coroner’s upcoming release, a first new single entitled “Renewal” is being made available today. Check it out in a video clip directed by Dariusz Szermanowicz / http://www.g13.film here: https://www.youtube.com/watch?v=3O8PtResaY8

Coroner’s guitarist, songwriter and producer Tommy Vetterli checked in with the following comment about the band’s new music:

“I thought a lot about what Coroner should sound like today, but I pretty quickly realized that looking backwards wouldn’t serve us. Of course, over time you develop a certain signature as a musician. So even if the material is new, it might still feel like a bridge to earlier phases – simply because it’s me writing it.

That said, we didn’t set out to continue a legacy. We just wanted to create something honest and grounded in the present. ‘Renewal’ now opens the chapter for what became the first Coroner album I’m fully satisfied with, start to finish. So we’ll let the music speak for itself – you’ll know if it speaks to you.”

“Dissonance Theory” contains 10 new songs across 47 minutes, recorded by Tommy Vetterli at New Sound Studios in Switzerland and mixed/mastered by Jens Bogren at Fascination Street Studios in Sweden (Opeth, Kreator, Amon Amarth, etc.). The album’s cover artwork (to be seen above) was created by Stefan Thanneur. Here is the standard track-listing of the upcoming album:
