"Atom Heart Mother" is a six-part suite by progressive rock band Pink Floyd, composed by all members of the band and Ron Geesin. It appeared on the Atom Heart Mother album in 1970, taking up the whole first side of the original vinyl record. It is Pink Floyd's longest uncut piece (the later "Shine On You Crazy Diamond", though longer, was split between two sides of Wish You Were Here.) Pink Floyd performed it live between 1970 and 1972, occasionally with a brass section and choir in 1970-71.
Performed by Conservatoire National supérieur de musique et de danse de Paris (CNSMDP) in March of 2003.
