The Dark Side of the Moon by Pink Floyd

The Dark Side of the Moon is the eighth studio album by the English progressive rock band Pink Floyd, released on 1 March 1973 by Capitol Records in the US and on 16 March 1973 by Harvest Records in the UK. Developed during live performances before recording began, it was conceived as a concept album that would focus on the pressures faced by the band during their arduous lifestyle, and also deal with the mental health problems of the former band member Syd Barrett, who had departed the group in 1968. New material was recorded in two sessions in 1972 and 1973 at EMI Studios in London.
