The story behind
Pink Floyd recorded Another Brick in the Wall, Part 2 in 1979 as part of The Wall, an album that became a sort of musical novel. The song is the second part of a trilogy, and it focuses on the idea of how the educational system can be oppressive. The lyrics talk about a boy who suffers from his overprotective mother and abusive teachers, and those traumas become bricks of a wall that is being built in his mind.
The song includes a choir of children that adds to the rhythm, something that was achieved thanks to a producer who suggested incorporating elements of a disco. It was an international success, reaching the top of the charts in several countries and being nominated for a Grammy. The recording of the choir was complicated, because the children had to practice a bit and the school principal wasn't aware at first. The idea was that the kids would feel part of something bigger, not just listening to music.
