Cream were a 1960s British rock supergroup power trio consisting of bassist/singer Jack Bruce, drummer Ginger Baker, and guitarist/singer Eric Clapton. Their sound was characterised by a hybrid of blues rock, hard rock and psychedelic rock, combining the psychedelia-themed lyrics, Eric Clapton's blues guitar playing and vocals, Jack Bruce's voice and prominent bass playing and Ginger Baker's jazz-influenced drumming. The group's third album, Wheels of Fire, was the world's first platinum-selling double album.
