Recorded at Abbey Road Studios and released in October 1970, Atom Heart Mother was Pink Floyd's first #1 album in the UK. The epic 23-minute title track, which constitutes all of the first side of the LP, was a grandiose sonic exploration in six movements. Side two featured one track each composed by Roger Waters, Richard Wright and David Gilmour, rounded out by "Alan's Psychedelic Breakfast", which was composed by the band as a whole.
