Kevin Michael "GG" Allin was an American punk rock musician who performed and recorded with many groups during his career. His live performances often featured transgressive acts, including self-mutilation, defecating on stage, and assaulting audience members, for which he was arrested and imprisoned on multiple occasions. AllMusic called him "the most spectacular degenerate in rock n' roll history", while G4TV's That's Tough labelled him the "toughest rock star in the world".
Known more for his notorious stage antics than his music, Allin recorded prolifically, not only in the punk rock genre, but also in spoken word, country, and more traditional-style rock. His lyrics often expressed themes of violence and misanthropy.
Allin's music was often poorly recorded and produced, given limited distribution, and met with mostly negative reviews from critics, although he maintained a cult following throughout and after his career. Allin promised for several years that he would commit suicide on stage during one of his concerts, but he instead died from a drug overdose on June 28, 1993, at age 36.
