Did you know that the Simon and Garfunkel song "The Sound of Silence" did not become a hit until it was remixed? The song was originally released in March 1964 on the album Wednesday Morning, 3 AM in an acoustic version. The album did not do well and the duo broke up. The song "The Sound of Silence" did not attract airplay until spring 1965. The song's producer, Tom Wilson, noticed the popularity and then remixed the track overdubbing electric instrumentation. Simon & Garfunkle were not told about the remix until after it was released. The remixed song hit number one on the Billboard Hot 100 in December 1965. The duo then reunited and recorded their second album titled Sounds of Silence.
