Pink Floyd пен Рон Джизиннің «Atom Heart Mother» композициясы

Musical composition by Pink Floyd and Ron Geesin

"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. When Roger Waters heard David Gilmour playing the guitar parts for this track, he said that he thought it sounded like the theme song from the western film The Magnificent Seven. The track was one of only two Pink Floyd compositions credited as being co written by someone outside the band prior to 1987 (not counting Clare Torry's contribution to "The Great Gig in the Sky", for which she was retroactively credited, following a settlement with Pink Floyd). Kubrick did, however, include the album cover in the film. It can be seen on a shelf in the music shop scene. Years later, Kubrick refused Roger Waters permission to use audio samples from his film 2001: A Space Odyssey on Waters' solo album Amused to Death.

The band were initially enthusiastic about performing the suite. An early performance was taped for the San Francisco television station KQED, featuring just the band, on 28 April 1970. Two major performances were at the Bath Festival of Blues and Progressive Music on 27 June and the "Blackhill's Garden Party" in Hyde Park, London on 18 July, convened by the band's erstwhile management partnership, Blackhill Enterprises. On both occasions the band were accompanied by the John Alldis Choir and the Philip Jones Brass Ensemble. Later, the band took a full brass section and choir on tour just for the purpose of performing this piece. However, this caused the tour to lose money, and the band found problems with the hired musicians, which changed from gig to gig as they simply took who was available, which, combined with lack of rehearsal and problems miking up the whole ensemble, made a full live performance more problematic. Reflecting on this, Gilmour said "some of the brass players have been really hopeless". According to Mason, the band arrived at one gig in Aachen, Germany, only to discover they had left the sheet music behind, forcing tour manager Tony Howard to go back to London and get it. A later arrangement without brass or choir, and pared down from 25 minutes to fifteen by omitting the "collage" sections and closing reprise of the main theme, remained in their live repertoire into 1972. The first live performance of The Dark Side of the Moon suite in Brighton was abandoned partway through; after a break, the band played Atom Heart Mother instead. Pink Floyd's last live performance of the suite took place on 22 May 1972 at the Olympisch Stadion, Amsterdam, Netherlands. The number was performed live on 14 and 15 June 2008 by The Canticum Choir, conducted by Mark Forkgen, with the Royal College of Music on brass, Caroline Dale on cello, Ron Geesin on piano, Andrea Beghi on drums, Nadir Morelli on bass, Federico Maremmi on guitar and Emanuele Borgi on the Hammond organ. David Gilmour joined the ensemble on the second night at Cadogan Hall playing his black Stratocaster for most of the track and lap steel guitar for the slide parts. The suite had been previously performed by a number of ensembles including the Conservatoire national supérieur de musique et de danse de Paris (CNSMDP) in March 2003 and the Seamus Band on 14 October 2005. Nick Mason's Saucerful of Secrets performed a section of the track on their 2018, 2019 and 2022 tours.

The working title for this piece changed a few times during the composing and recording process. When the first main theme was composed, David Gilmour called it "Theme from an Imaginary Western". The first working title for the six part piece was "Epic", written in Ron Geesin's handwriting at the top of his original score. The work was introduced at the 27–28 June 1970 Bath Festival of Blues and Progressive Music as "The Amazing Pudding". In July 1970 Ron Geesin pointed Roger Waters to the 16 July 1970 edition of the Evening Standard and told him that he would find the song title in the newspaper. Waters saw an article, on page 9, about a woman who had been fitted with a plutonium powered pacemaker. The headline was "".

The live recording at the Montreux Casino (from The Early Years box set) also features on the shorter compilation The Early Years 1967–1972: Cre/ation. An edited version of this song was considered for the album Echoes: The Best of Pink Floyd, but did not make the final track listing.

While the band themselves have expressed negative opinions of the album in recent memory, others, like Irving Tan of Sputnik Music enjoyed the track. In 2011, PopMatters ranked "Atom Heart Mother" as the 25th greatest progressive rock song of all time.

The album The Dark Side of the Moog III (1995) by Klaus Schulze and Pete Namlook is subtitled "Phantom Heart Brother". Their later album The Dark Side of the Moog IX (2002) is subtitled "Set the Controls for the Heart of the Mother".
