John Davies Cale is a Welsh musician, composer, and record producer who was a founding member of the American rock band the Velvet Underground. Over his six-decade career, Cale has worked in various styles across rock, drone, classical, avant-garde and electronic music.

The Velvet Underground was an American rock band formed in New York City in 1964. It originally comprised singer and guitarist Lou Reed, Welsh multi-instrumentalist John Cale, guitarist Sterling Morrison, and drummer Angus MacLise. In 1965, MacLise was replaced by Moe Tucker, who played on most of the band's recordings. Though their integration of rock and the avant-garde resulted in little commercial success, they became one of the most influential bands in rock, underground, experimental, and alternative music. Their provocative subject matter, musical experiments, and nihilistic attitude was also instrumental in the development of punk rock, new wave and several other genres.
