Andy Warhol is of course primarily known as a major visual artist, and a significant filmmaker. He was not a musician, and probably knew little about the technological processes by which music is recorded. Nonetheless, he made notable contributions to rock history as a producer and manager of the Velvet Underground. He managed the Velvets until about the summer of 1967, and was credited as producer of the bulk of their debut album.
Although Warhol was about 15 to 20 years older than the members of the Velvet Underground, he did have a considerable enthusiasm for rock music before he met them. (It has been said that his favorite single was the Jaynetts' girl-group classic "Sally Go Round the Roses").
