For nearly a quarter century, Deterioration – comprised of brothers Jim and Joe Kahmann – has stood as a relentless force in extreme music. With over 75 physical releases and thousands of live performances across North and South America, the duo has honed, refined, and weaponized their own unmistakable strain of punishing, industry-leading Brutal Midwest Grindcore. Uncompromising, unrelenting and unapologetic: Deterioration sonically bulldozes everything and everyone in their path.
