Music like atom heart mother

"Atom Heart Mother" is a six-part suite by the 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 first side of the original vinyl record. At 23:38, 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.

Recording began with the drum and bass parts, recorded in one take for the entire suite, resulting in an inconsistent tempo throughout the song. Roger Waters and Nick Mason had to play for twenty-three minutes straight.
