What a guitar riff … Classic Clapton/Cream. “Psychedelic Rock”
“Sunshine of Your Love” is a 1967 song by the British rock band Cream. With elements of hard rock, psychedelia, and pop, it is one of Cream’s best known and most popular songs. Cream bassist and vocalist Jack Bruce based it on a distinctive bass riff he developed after attending a Jimi Hendrix concert. Guitarist Eric Clapton and lyricist Pete Brown later contributed to the song. Recording engineer Tom Dowd suggested the rhythm arrangement in which drummer Ginger Baker plays a distinctive tom-tom drum rhythm, although Baker claimed it was his idea.
The song was included on Cream’s second album Disraeli Gears in November 1967, which was a best seller. Atco Records, the group’s American label, was initially unsure of the song’s potential. After recommendations by other label-affiliated artists, it released an edited single version in December 1967. The song became Cream’s first and highest charting American single and one of the most popular singles of 1968. In September 1968, it became a modest chart hit after being released in the UK.
