Like jazz, rock and roll has made use of tone clusters since its birth, if characteristically in a less deliberate manner—most famously, Jerry Lee Lewis's live-performance piano technique of the 1950s, involving fists, feet, and derrière. Since the 1960s, much drone music, which crosses the lines between rock, electronic, and experimental music, has been based on tone clusters. On The Velvet Underground's "Sister Ray," recorded in September 1967, organist John Cale uses tone clusters within the context of a drone; the song is apparently the closest approximation on record of the band's early live sound. Around the same time, Doors keyboardist Ray Manzarek began introducing clusters into his solos during live performances of the band's hit "Light My Fire."
