The epic sweep of Plastic Surgery Disasters, in both sonic texture and thematic depth, sets it apart as one of punk's most highly evolved musical and artistic statements. Vocalist Jello Biafra's rage had developed into a calmer but more strident kind of anger. Fortified by a wider variety of sounds, including horns, clarinets, and east bay ray's rich palette of aggressive guitar textures, this album attacked the usual Dead Kennedys targets.
