Some bands thrive in the safety of the recording studio, away from the chaotic energy of a live audience. But Pink Floyd mastered both with remarkable flair.

Pink Floyd's "When The Tigers Broke Free" is one of the band's most personal songs. Maybe too personal, as it was years before many heard it.

Pink Floyd's Comfortably Numb, the U.K. platinum-selling third single from 'The Wall,' was released on June 23, 1980.
