Roger Waters, the lyrical mastermind behind most of Pink Floyd’s work in the 1970s, was the band’s bassist, vocalist and, at one point, its front man. He solidified himself as one of music’s greatest poets with Animals, a picture of modern society metaphorized as animals, and The Wall, an epic rock opera that follows a rockstar’s declining mental state and disillusionment with the world around him.

After leaving Pink Floyd, he went on to create even more works that geared towards geopolitical themes, with the electrifying Radio K.A.O.S. and the provoking Amused to Death.
