Raymond John Pepperell, more commonly known by the stage name "East Bay Ray", is an American musician who plays guitar for the San Francisco Bay area-based punk band Dead Kennedys. His guitar work was influenced by jazz and rockabilly. Alongside Jello Biafra's astute lyrics and unique vibrato-based vocal style, East Bay Ray's playing was one of the defining factors of the music of the Dead Kennedys, and by extension, of the "second wave" of American punk.
