Whether it’s the mystifying hourglass of parenthood or a sudden collision of earth to brain, time erodes both in steady, unnoticeable stutters and blink-speed slides.1 I’m sure Coroner never quite planned to sit this long on new material, with its inception a decade ago sliding to present today in maturity. But after thirty-plus years, there’s little rush in releasing anything for the sake of the release itself. In thoughtful construction, a composed comeback will warrant discussion upon emergence and later on down the road. And with Dissonance Theory, both a foot in a deep thrash history and desire to explore a progressive sound, Coroner seeks to prove that a vital record can still exist under their storied name.
While the aged gap between albums presents as a hurdle to momentum, Coroner hasn’t been dormant leading up to Dissonance Theory, a healthy festival and gig routine since 2010 stoking their creative flame. And cornerstone guitarist Tommy Baron has remained engaged in studio management while weaving through extra-Coroner band activities over the years, like his brief stint with fellow thrash legends Kreator in the late ’90s2 or his more modern chug-a-lug with the alternative/industrial-laced 69 Chambers. Along this timeline, then, it makes sense that Dissonance Theory presents not as a widening of the take-it-or-leave-it Grin but as an exploration of how history has shaped their own interpretation of their sound. Lower-tuned tap ‘n’ go strides follow the splinter that spiraled dark groove machines like Nevermore and Morgana Lefay (“Consequence,” “Symmetry,” “Renewal”). Heavier anthemic numbers mirror the booming stadium feel of modern Kreator (“Sacrificial Lamb”), even verging on Lamb of God thrash-thuggery at its most simple (“Crisium Bound”). Many faces have worn Coroner over the years, but Coroner wearing them back reveals new wrinkles.
Yet Dissonance Theory hits what makes modern Coroner a force when layered guitar textures and screaming solos have space to warp and twist about dips into classic thrash breaks and screaming solos. Baron has always been an expressive guitarist. But in the long road since the Celtic Frosted days of RIP, he’s found a way both to whip the frenetic scramble of a pit-ready bridge into heroic fretboard gymnastics (“Consequence,” “Symmetry”) and drop jaws with melodic, bluesy tone-wailing (“Transparent Eye”). Likewise, jangling chords find resonant space and careful modulation in pocketed drum rhythms and steady, growling bass, showcasing the careful ear for harmony that Coroner has always endorsed (“The Law,” “Transparent Eye”). And though a couple tracks may use their space less effectively than others, finding a slight meandering in their joy of sound, Dissonance Theory breezes by in a veteran flex of songwriting maturity.
However, I take some issue with the ways in which the Bogren production job bolsters Coroner into the modern day. Again, part of what makes Coroner, well, Coroner is a vibrant guitar identity that twangs and twirls and cuts with buttery precision. And while a nasally compression still helps to define the chatter of Dissonance Theory’s most thrashing moments (“Consequence,” “Symmetry”), more weight finds a home in a thick and pulverizing rhythm tone. Ron Royce’s thick-stringed assault, naturally, finds a happy home with the lean into low-end emboldening, and that partnering with the muddier rhythm tone finds a unison richness on certain brooding runs (“Sacrificial Lamb” through “Symmetry”). Furthermore, new drummer Diego Rapacchietti finds a powerful march and kick clamor that creates a playful propulsion against bright, palm-muted runs (“Sacrificial Lamb,” “The Law”). Against the flat rhythm guitar characterization, alas, all of these production accents don’t always add up to song sections that feel distinct over the whole of the album.
Coroner’s influence continues to ripple through thrashy and deathly forms alike despite the current day being far removed from their initial declarations. But more importantly, Dissonance Theory proves that in 2025, Coroner has been paying attention to their progeny in order to shape a new face for the flock of hopefuls to follow. I don’t think Dissonance Theory carves quite as deep a notch as the Swiss stalwarts had hoped, though in its collective wisdom, it can be hard to put down. As first steps in a new direction, Dissonance Theory fills me with hope that a Coroner second coming will bear fruit at least once more with a greater level of determination.
