Lifehouse is an unfinished science fiction rock opera by The Who intended as a follow-up to Tommy. It was abandoned as a rock opera in favour of creating the traditional rock album Who's Next, though its songs would appear on various albums and singles by the Who, as well as Pete Townshend solo albums. In 1978, aspects of the Lifehouse project were revisited by the Who on Who Are You. In 2000, Townshend revived the Lifehouse concept with his set Lifehouse Chronicles and the sampler Lifehouse Elements. On 1 May 2007, he released an online software called The Lifehouse Method in which any "sitter" could create a musical "portrait". The site is now defunct.

Another source of inspiration for Townshend was Meher Baba, who claimed to be an avatar of Brahman. What Townshend was aiming to achieve in Lifehouse was to write music that could be adapted to reflect the personalities of the audience. To do this he wanted to adapt his newly acquired hardware, VCS3 and ARP synthesisers and a four-channel quadraphonic PA system, to create a machine capable of generating and combining personal music themes written from computerised biographical data. Ultimately, these thematic components would merge to form a "universal chord". To help this process, the Who would encourage individuals to emerge from the audience and find a role in the music. The Lifehouse concept Lifehouse began as a story written around several songs. According to Pete Townshend: "The essence of the story-line was a kind a futuristic scene…It’s
