Carlos Cadona, better known by his stage name 6025, is (or possibly was) an American musician who served as the second guitarist for the American punk rock band Dead Kennedys, from their formation in July 1978 to March 1979. Although he is sometimes claimed to have been considered as a drummer or singer, frontman Jello Biafra has stated that 6025 was recruited solely as a guitarist. Initially the band was a quartet, consisting of bassist Klaus Flouride, vocalist Biafra, guitarist East Bay Ray, and drummer Bruce Slesinger, all of whom had answered an ad placed by Ray. 6025 was added to the line-up only a week before their first live performance, which took place on July 19, 1978. Due to his very short tenure in the band and disappearance from the public eye almost immediately thereafter, very little is known about him, and the circumstances surrounding his departure from the band remain contested.
