The Wall was Roger Waters' crowning accomplishment in Pink Floyd. It documented the rise and fall of a rock star (named Pink Floyd), based on Waters' own experiences and the tendencies he'd observed in people around him. This ambitious concept album was an across-the-board smash, topping the Billboard album chart for 15 weeks in 1980. The single "Another Brick in the Wall, Pt. 2" was the country's best-seller for four weeks. The Wall spawned an elaborate stage show (so elaborate, in fact, that the band was able to bring it to only a few cities) and a full-length film. It also marked the last time Waters and Gilmour would work together as equal partners.
