Derek and the Dominos was a music group formed in the spring of 1970 by guitarist and singer Eric Clapton along with Bobby Whitlock, Carl Radle and Jim Gordon, who had all played with him in Delaney & Bonnie & Friends. Duane Allman from the Allman Brothers Band joined the group early in the recording of their first album. They were a blues-rock band that demonstrated virtuosity at its finest, showing some of Eric "Slowhand" Clapton's finest work. The group debuted at the Lyceum Theatre in London on June 14, 1970 where the announcer mispronounced their provisional name of Eric and the Dynamos to Derek and the Dominos, the band decided to take up the new name and undertook a summer tour of England.
