Review CORONER “Dissonance Theory”

I think many metalheads didn’t expect a new album from Swiss metal icons Coroner. The band has played numerous live shows in recent years, including festival appearances and a North American tour. However, a new album is another matter entirely, and the idea of such a release seemed far-fetched. But sometimes fantasy becomes reality. A few months ago, Coroner announced a new album called “Dissonance Theory,” and here it is.

“Dissonance Theory” is Coroner’s first album in 32 years; the last one was “Grin” in 1993, which closed the first chapter of the band’s releases. Tom Vetterli, Ron Broder, and Diego Rapacchietti are now back with nine new songs, plus an intro, all of which are summarized as “Dissonance Theory.” What the trio delivers connects directly to what the band delivered more than three decades ago.

As in the early days, the new album combines heaviness with clockwork precision and a great feel for superb songs. “Oxymoron” is the eerie opener, and “Consequence” is the first sonic blast.

“Consequence” brings back the sound of the ’90s with a contemporary touch. Massive riff attacksalternate with acoustic moments, all presented with technical perfection, as does “Sacrificial Lamb.” Despite its various layers, the song sounds like a metal monolith bursting with creativity. At a moderate pace, “Sacrificial Lamb” unveils its dark bloom when you listen to “Dissonance Theory” for the first time.

“Crisium Bound” is a pulsating song that picks up the dark vibe from the previous track, before the heavily pounding “Symmetry” unleashes its addictive groove. The song reflects all the Coroner trademarks while spreading a modern vibe with a superbly crafted guitar solo.

The calmer start of “The Law” contrasts with the previous song, providing a peaceful moment that turns into the next gloomy riff monster. This song impresses with its riff power and gives you the shivers with its sinister chorus. “Transparent Eye” is a slower-paced riff behemoth with an evil grin. It is the perfect example of how Coroner combines a technically sophisticated song structure with heaviness and modern-day melodic features, allowing for an immediate connection and lasting listening pleasure.

The grim riffs of “Trinity” lead to “Renewal” with its wrecking ball–like start. There is little flourish at the beginning. Instead, the riff hits you right in the face, and with its aggressive foundation, Coroner shows off their musical prowess. “Renewal” is, in a way, also what the album represents. While sticking to their roots and trademark sound, Coroner brings their unique features into the 21st century. Referring to their roots while embracing the present is what “Dissonance Theory” expresses through each song of this thrilling tracklist.

It should not surprise anyone that Coroner maintains a high quality level until the end. The closer, “Prolonging,” is another jaw-dropping moment. I did not expect to hear the sound of the Hammond organ on this album, but it fits perfectly into the band’s musical vision.

Coroner is back with full force. Three decades without a new album was a tough time for fans, but the good news is that “Dissonance Theory” is a stunning new album from a veteran band. Coroner in 2025 exude strength and energy, with an overall atmosphere of creativity and happiness from beginning to end. Tommy Vetterli, Ron Broder, and drummer Diego Rapacchietti provide the same jaw-dropping soundscapes as in their early years. This album is a highlight of 2025 and beyond. Welcome back, Coroner!
