Wilson produced Simon & Garfunkel's 1964 debut LP "Wednesday Morning, 3 A.M." which included "The Sound of Silence". Seizing on local radio interest in the song in Florida and inspired by the huge success of the Byrds' folk-rock version of Dylan's "Mr Tambourine Man", Wilson took the duo's original acoustic track and, without Simon's or Garfunkel's knowledge, overdubbed electric instruments, turning the track into a #1 pop hit, helping to launch the folk-rock genre. Simon and Garfunkel, who had already split, re-united after the hit and went on to greater success.
