The Wall is the eleventh studio album by English rock band Pink Floyd, released 30 November 1979 on Harvest and Columbia Records. It is a rock opera that explores Pink, a jaded rockstar whose eventual self-imposed isolation from society is symbolized by a wall. The album was a commercial success, topping the US charts for 15 weeks, and reaching number three in the UK. It initially received mixed reviews from critics, many of whom found it overblown and pretentious, but later came to be considered one of the greatest albums of all time.
Bassist Roger Waters conceived The Wall during Pink Floyd's 1977 In The Flesh tour, modeling the character of Pink after himself and former bandmate Syd Barrett. Recording spanned from December 1978 to November 1979. Producer Bob Ezrin helped to refine the concept and bridge tensions during recording, as the band were struggling with personal and financial issues at the time. The Wall is the last album to feature Pink Floyd as a quartet; keyboardist Richard Wright was fired by Waters during production, but stayed on as a salaried musician. Three singles were issued from the album: "Another Brick in the Wall, Part 2" (the band's only US number-one single), "Run Like Hell", and "Comfortably Numb". From 1980 to 1981, Pink Floyd performed the full album on a tour that featured elaborate theatrical effects.
