See media help . </Td> </Tr> <P> Generally, all four members agreed that Waters' album concept unified by a single theme was a good idea . Waters, Gilmour, Mason and keyboardist Richard Wright participated in the writing and production of the new material, and Waters created the early demo tracks at his Islington home in a small studio built in his garden shed . Parts of the new album were taken from previously unused material; the opening line of "Breathe" came from an earlier work by Waters and Ron Geesin, written for the soundtrack of The Body, and the basic structure of "Us and Them" borrowed from an original composition by Wright for Zabriskie Point . The band rehearsed at a warehouse in London owned by The Rolling Stones, and then at the Rainbow Theatre in Finsbury Park, London . They also purchased extra equipment, which included new speakers, a PA system, a 28 - track mixing desk with four quadraphonic outputs, and a custom - built lighting rig . Nine tonnes of kit was transported in three lorries; this would be the first time the band had taken an entire album on tour, but allowed improvement and refinery nonetheless, which by then had been given the provisional title of Dark Side of the Moon (an allusion to lunacy, rather than astronomy). However, after discovering that that title had already been used by another band, Medicine Head, it was temporarily changed to Eclipse . The new material premièred at The Dome in Brighton, on 20 January 1972, and after the commercial failure of Medicine Head's album the title was changed back to the band's original preference . </P> <P> Dark Side of the Moon: A Piece for Assorted Lunatics, as it was then known, was performed in the presence of an assembled press on 17 February 1972--more than a year before its release--at the Rainbow Theatre, and was critically acclaimed . Michael Wale of The Times described the piece as "...bringing tears to the eyes . It was so completely understanding and musically questioning ." Derek Jewell of The Sunday Times wrote "The ambition of the Floyd's artistic intention is now vast ." Melody Maker was, however, less enthusiastic: "Musically, there were some great ideas, but the sound effects often left me wondering if I was in a bird - cage at London zoo ." However, the following tour was praised by the public . The new material was performed live, in the same order in which it would eventually be recorded, but obvious differences between the live version, and the recorded version released a year later, included the lack of synthesizers in tracks such as "On the Run", and Bible readings that were later replaced by Clare Torry's non-lexical vocables on "The Great Gig in the Sky". </P>
