"Another Brick in the Wall" is a three-part composition on Pink Floyd's 1979 rock opera The Wall, written by bassist Roger Waters. "Part 2", a protest song against corporal punishment and rigid and abusive schooling, features a children's choir. At the suggestion of producer Bob Ezrin, Pink Floyd added elements of disco.

Pink Floyd are an English rock band formed in London in 1965. Gaining an early following as one of the first British psychedelic groups, they were distinguished by their extended compositions, sonic experiments, philosophical lyrics and elaborate live shows. They became a leading band of the progressive rock genre, cited by some as the greatest progressive rock band of all time.
