The Wall is the eleventh studio album by the English progressive rock band Pink Floyd. It is the last studio album released with the classic lineup of guitarist David Gilmour, bassist/lyricist Roger Waters, keyboardist Richard Wright and drummer Nick Mason before Wright left the band. Released as a double album on 30 November 1979, it was supported by a tour with elaborate theatrical effects, and adapted into a 1982 feature film, Pink Floyd – The Wall. The album features the band's only number one single "Another Brick in the Wall Part 2".
As with Pink Floyd's previous three albums, The Wall is a concept album and explores themes of abandonment and personal isolation. The album is a rock opera that follows Pink, a character whom Waters modelled after himself and the band's original leader, Syd Barrett. Pink's life begins with the loss of his father during the Second World War and continues with abuse from his schoolteachers, an overprotective mother, and the breakdown of his marriage; all contribute to his eventual self-imposed isolation from society, represented by a metaphorical wall. Waters conceived the album during Pink Floyd's 1977 In the Flesh Tour, when his frustration with the audience became so acute that he imagined a wall between the audience and the stage.
