Simon and Garfunkel's "The Sound of Silence" has been selected as one of 25 recordings to be preserved at the U.S. Library of Congress. The track, which was originally released on the duo's first album, Wednesday Monring, 3 A.M., became a #1 hit in 1966 after Columbia Records producer Tom Wilson overdubbed drums, electric guitar and electric bass for the song’s release as a single. Recordings are added to the National Recording Registry for long-term preservation due to cultural, artistic and historic importance to the nation’s aural legacy.
