The Dark Side of the Moon (titled Dark Side of the Moon in the 1993 CD edition) is a concept album by the British progressive rock band Pink Floyd. It was released on March 17, 1973 in the U.S. and March 24, 1973 in the UK.
The Dark Side of the Moon builds upon previous experimentation Pink Floyd had done, especially on their album Meddle. Its themes include old age, conflict and insanity; the latter possibly inspired by the deteriorating mental state of their former band leader Syd Barrett. The album is notable for its use of musique concrète and conceptual, philosophical lyrics, as found in much of Pink Floyd's work.
