Dark Side of the Moon is the 8th studio recording by the English rock group, Pink Floyd. Released on Harvest records March 1, 1973, it abruptly propelled the band into the ranks of rock music's biggest acts. Its lyrical themes include conflict, greed, the passage of time, and mental illness. Enjoying both critical and commercial success, it remained on the Billboard Top 200 chart for 741 weeks, from 1973 to 1988, longer than any album in history, and sold an estimated 45 million copies worldwide. Dark Side is not only Pink Floyd's most successful album, it is often ranked as one of the greatest albums of all time. 
 
The Dark Side of the Moon LP included two posters folded inside: a green moonscape, and the band photo montage poster featured in this collection. It is hand-signed by the members of Pink Floyd: Roger Waters, David Gilmour, Nick Mason, and Richard Wright.
 
Their 1977 double album, The Wall, is a rock opera that has also been performed multiple times as an elaborate theatrical musical production by the band and by Roger Waters. It became the band's second-best selling album.
 
In 1982, an animated/live action film was released based on the album: Pink Floyd -- The Wall. Included in this collection is a single release from the film soundtrack, "When the Tigers Broke Free," by Roger Waters.
