The Who are an English rock band formed in London in 1964. Their classic lineup (1964–1978) consisted of lead vocalist Roger Daltrey, guitarist Pete Townshend, bassist John Entwistle, and drummer Keith Moon. Considered one of the most influential rock bands of the 20th century, their contributions to rock music include the development of the Marshall stack, large public address systems, the use of synthesisers, Entwistle's and Moon's influential playing styles, Townshend's feedback and power chord guitar technique, and the development of the rock opera. They are cited as an influence by many bands, particularly those in the hard rock, punk, power pop and mod genres. The group were inducted into the Rock and Roll Hall of Fame in 1990.

In 1967, they performed at the Monterey Pop Festival and released "I Can See for Miles", their only US top ten single. The group's 1969 concept album Tommy included the single "Pinball Wizard" and was a critical and commercial success. Further festival appearances at Woodstock and the Isle of Wight, along with the concert album Live at Leeds (1970), established their reputation as a respected rock act. The success put pressure on lead songwriter Townshend, and the follow-up to Tommy, Lifehouse, was abandoned. Songs from the project made up the album Who's Next (1971), including the hits "Won't Get Fooled Again", "Baba O'Riley", and "Behind Blue Eyes". The group released another concept album, Quadrophenia (1973), as a celebration of their mod roots, and oversaw the film adaptat
