the sound of silence

The song features Simon on acoustic guitar and both singing. It was originally recorded as an acoustic piece for their first album Wednesday Morning, 3 A.M. in 1964 but on the initiative of the record company's producer, Tom Wilson, it was later overdubbed with drums (Bobby Gregg), electric bass (Bob Bushnell) and electric guitar (Al Gorgoni), all without the knowledge or participation of Simon & Garfunkel and rereleased as a single in September 1965.[3][4] The single reached number one on New Year's Day 1966 and was included in the 1966 album Sounds of Silence.
