The eleventh studio album by the English rock band and one of the most acclaimed concept albums of all time, The Wall is renowned as Roger Waters' Rock Opera, dealing with abandonment and personal isolation. Featuring the unique artwork of Gerald Scarfe, the album contains the singles “Another Brick in the Wall, Part 2,” a No.1 hit in the UK and the US, “Run Like Hell” and “Comfortably Numb”. It was subsequently adapted for cinema by Alan Parker, featuring Bob Geldof in the lead role of Pink, a jaded rockstar whose eventual self-imposed isolation from society is symbolized by a wall.
