The Dark Side Of The Moon sold 25 million copies in its first 25 years of release. It continues to be a favourite. The album was developed as part of a forthcoming tour of live performances, and premièred several months before studio recording began. The new material was further refined during the tour, and was recorded in two sessions in 1972 and 1973 at Abbey Road Studios in London. Pink Floyd used some of the most advanced recording techniques of the time, including multitrack recording and tape loops. Analogue synthesizers were given prominence in several tracks, and a series of recorded interviews with staff and band personnel provided the source material for a range of philosophical quotations used throughout. Engineer Alan Parsons was directly responsible for some of the most notable sonic aspects of the album, including the non-lexical performance of Clare Torry.

The Dark Side of the Moon was an immediate success, topping the Billboard 200 for one week. It subsequently remained on the charts for 741 weeks (fourteen years), the longest duration of any album in history. With an estimated 45 million units sold, it is Pink Floyd's most commercially successful album and one of the best-selling albums worldwide. It has twice been remastered and re-released, and has been covered by several other acts. It spawned two singles, "Money" and "Us and Them". In addition to its commercial success, The Dark Side of the Moon is one of Pink Floyd's most popular albums among fans and critics and is frequently ranked as one of the greatest rock albums of all-time.
