Deterioration ruled the stage at Jannus Live, according to RØKKR's Brian Folchetti

Deterioration's opening set at Jannus Live in St. Petersburg, Florida, in 2026 was part of a bill on the Dying Fetus and Sanguisugabogg tour. It is worth revisiting now because RØKKR's Brian Folchetti wrote one of the most enthusiastic reviews the act's live show has received. The piece was published on 22 October 2026 and concentrated on what happened on stage rather than on background.

Folchetti framed the evening as one of mayhem in a packed venue, with the opening set standing out as part of a bill that kept the room moving. What he responded to most was the sound. He described the duo's output as an unrelenting wall of sound, a phrase that reads as praise for density, pace and sheer force rather than as a note on subtlety.

The vocals were the one element he singled out for a sharper remark. Jim Kahmann's delivery was characterised as shrill, a word that might sit uneasily in a glowing review. The critic did not, however, treat it as a flaw that undermined the performance. It was one of the textures he noted within a set he judged strongly favourable overall.

The verdict was unambiguous. Folchetti concluded that Deterioration performed exceptionally well on the night and that the band absolutely ruled the stage. The review carries no numerical rating, so its weight rests entirely on the prose, and that prose leaves little doubt about where the critic stood.

For readers who know the act mainly through recordings, the piece offers a useful snapshot of how Deterioration comes across live: loud, relentless and dense. It is also a reminder that support slots can produce vivid writing, and that a critic's enthusiasm for an opener can be as telling as praise for the headliners.
