The Who are an English rock band, formed in 1964. The most notable line-up consisted of singer Roger Daltrey, guitarist Pete Townshend, bassist John Entwistle, and drummer Keith Moon. For much of their career they have been regarded as the third most important British rock act after The Beatles and The Rolling Stones.
The band developed from an earlier group, The Detours, playing a mix of rock 'n' roll and rhythm and blues, before stabilizing around a line-up of Daltrey, Townshend, Entwistle and Moon. After releasing a single (billed as The High Numbers), the group established themselves as part of themod movement, specialising in auto-destructive art by destroying guitars and drums onstage. The group achieved national attention in Britain after support by pirate radio and television, with their first single (as The Who), "I Can't Explain" reaching the top ten, and achieved a number of further hits including "My Generation", "Substitute" and "Happy Jack". The group achieved success in the US after performing at the Monterey Pop Festival in 1967, and the top ten single "I Can See for Miles", and spent much of the following year touring there.
