The Who are an English rock band formed in 1964. Their best known line-up consisted of lead singer Roger Daltrey, guitarist Pete Townshend, bassist John Entwistle and drummer Keith Moon. For much of their career they have been regarded as one of the three most important British rock acts along with the Beatles and the Rolling Stones.
The Who developed from an earlier group, the Detours, before stabilising around a line-up of Daltrey, Townshend, Entwistle and Moon. After releasing a single, the group established themselves as part of the mod movement, specialising in auto-destructive art by destroying guitars and drums onstage. They achieved recognition in the UK after support by pirate radio and television, and their first single, "I Can't Explain" reached the top ten. A string of hit singles followed including "My Generation", "Substitute" and "Happy Jack". Although initially regarded as a singles act, they also found success with the albums My Generation and A Quick One. In 1967, they achieved success in the US after performing at the Monterey Pop Festival, and with the top ten single "I Can See for Miles". They released The Who Sell Out at the end of the year, and spent much of 1968 touring the US.
