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