Who's Next is the fifth studio album by The Who, released on 14 August 1971. Its origins lie in an abortive multi-media rock opera written by chief songwriter Pete Townshend called Lifehouse. The album was commercially and critically successful, and became the only one by the group to top the UK charts. These 50th anniversary editions are available on Coke Bottle Clear 180gm vinyl LP and half-speed mastered 180gm black vinyl LP.
