"The Dark Side of the Moon," Pink Floyd (1973)

After trying out the songs for their 1973 album while on tour, the progressive rock band Pink Floyd used the technology of the recording studio -- 16-track recorders, tape loops, synthesizers -- to produce this sonically celebrated album, which features subject matter decidedly darker than what was found on the band's earlier, psychedelic rock albums. Recorded at London's Abbey Road Studios by engineer Alan Parsons, "Dark Side of the Moon" is one of the best-selling albums ever, with more than 50 million copies sold. Its memorable songs include "Money," "Time," and "Us and Them."
