Who's Next is the fifth studio album by English rock band the Who. It developed from the aborted Lifehouse project, a multi-media rock opera written by the group's Pete Townshend as a follow-up to the band's 1969 album Tommy. The project was cancelled due to it's complexity and conflicts with Kit Lambert, the band's manager, but Townshend was persuaded to record the songs as a straightforward studio album. The Who recorded Who's Next with assistance from recording engineer Glyn Johns.
