Who's Next is the fifth studio album by the English rock band the Who, released on 14 August 1971.
It developed from the aborted Lifehouse project, a multi-media rock opera conceived by the group's guitarist Pete Townshend as a follow-up to the band's 1969 album Tommy.
The project was cancelled owing to its complexity and to conflicts with Kit Lambert, the band's manager, but the group salvaged some of the songs, without the connecting story elements, to release as their next album.
Eight of the nine songs on Who's Next were from Lifehouse, with the lone exception being the John Entwistle-penned "My Wife".
Ultimately, the remaining Lifehouse tracks would all be released on other albums throughout the next decade.
