The Who are an English rock band that first formed in 1964 and grew to be considered one of the greatest and most influential bands in the world. They are also famed for their prowess as a live band - winning awards and being described as "possibly the greatest live band ever." The primary lineup consisted of Pete Townshend (lead guitar, vocals), Roger Daltrey (lead vocals), John Entwistle (bass) and Keith Moon (drums).

The Who rose to fame in the United Kingdom with a pioneering instrument destruction stage show, as well as a series of top ten hit singles (including the celebrated "My Generation") and top five albums, beginning in 1965 with "I Can't Explain". They first hit the top ten in the USA in 1967 with "I Can See for Miles". The 1969 release of Tommy was the first in a series of top five albums for the group in the USA, followed by Live at Leeds (1970), Who's Next (1971), Quadrophenia (1973), and Who Are You (1978) among others.

Keith Moon died in 1978. After that the band released two more studio albums, the top five Face Dances (1981) and the top ten It's Hard (1982), with drummer Kenney Jones, before officially disbanding in 1983. They reformed on several occasions to perform at special events such as Live Aid and for reunion tours such as their 25th anniversary tour (1989) and the Quadrophenia revival tours of 1996 and 1997. In 2000, the three surviving original members began to discuss the possibility of recording an album of new material. These plans were delayed following the death of John Entwistle in 2002. Pete Townshend and Roger Daltrey continue to perform as The Who. In 2006 they released the studio album Endless Wire, which reached the top ten in the USA and UK.
