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.
The Who experienced significant success, artistic growth, and some challenges during the 1970s, a decade that solidified their status as one of the most influential rock bands in history. Their contributions to rock music include the development of the Marshall stack, large public address systems, the use of synthesizers, Entwistle’s and Moon’s influential playing styles, Townshend’s feedback and power chord guitar technique, and the development of the rock opera.
In 1978, Keith Moon died from an overdose of prescription medication at the age of 32. His death marked the end of an era for the band and posed challenges for their future.
