Background information: In 1964 Paul Simon and Art Garfunkel returned to the studio to record the album Wednesday Morning, 3 A.M. to record.   In contrast to the following albums, the composers were even more spread out here, for example there was a cover version of Bob Dylan's song The Times They Are a-Changin' and two traditionals. The cover was mostly black, featured the title in the top half and a picture of Simon and Garfunkel in the 5th Avenue station of the New York City subway in the bottom half. The entire album was recorded entirely with acoustic instruments and contained the first released version of the later hit The Sound of Silence (which was initially titled The Sounds of Silence). Although this album sold significantly better than its predecessor, the commercial breakthrough was still a long time coming.   However, the “division of roles” was already established with this album: Paul Simon was responsible for the music, Art Garfunkel for the vocals. His voice gives many of Simon and Garfunkel's pieces their unmistakable character. ​ Paul Simon spent the next few months in England, where, among other things, he recorded the album The Paul Simon Songbook for the BBC in just over an hour. This album was only sold moderately in Great Britain, but Paul Simon made a name for himself in the English folk scene and was able to charge up to 20 pounds per evening (around 200 euros today). During this time, Simon wrote several songs that were later recorded by Simon and Garfunkel. ​​​​
