The Wall (1979)

Roger Waters's double album follows Pink, a rock star building a psychological wall out of loss, schooling and fame. The three parts of Another Brick in the Wall turn up at different stages in different moods, from Part 1's sparse, echoing guitar to Part 2's disco-tinged protest. Comfortably Numb is the emotional peak; it hits hardest in its place in the sequence rather than on shuffle.
