New Yorkers Paul Simon & Art Garfunkel began as a late-1950s doo-wop group called Tom & Jerry. In the '60s, they turned to folk, with an extended stay in London bringing a heavy British folk influence into Simon's work. When a rock band was overdubbed onto the original acoustic version of their single "The Sounds of Silence," a hit resulted and helped further the then-nascent folk-rock movement. The pair's subsequent albums produced a long stream of catchy-but-brainy hit singles and also explored various musical styles, foreshadowing the eclecticism of Simon's solo career. Although the duo split after 1970's BRIDGE OVER TROUBLED WATER, they have reunited for performances on a few occasions, including a tour in 2003.
