Obscured by Clouds
Following Barrett's departure and replacement by David Gilmour, Wright took over writing duties with Waters but gradually became less involved as a singer and songwriter as the band's career progressed. His organ playing remained an important part of the band's live set, particularly on "Interstellar Overdrive", "Set the Controls for the Heart of the Sun" and "Careful with That Axe, Eugene". He contributed themes for the Pink Floyd film scores "More", "Zabriskie Point" and "Obscured by Clouds". He made significant arranging contributions to longer compositions such as "Atom Heart Mother", "Echoes" (on which he sang lead vocals with Gilmour) and "Shine On You Crazy Diamond". On 1973's "The Dark Side of the Moon" he composed the music for "The Great Gig in the Sky" and "Us and Them". He also contributed to the composition of other album tracks such as "Breathe" and "Time", singing lead vocals on the latter's chorus.
