The Atom Heart Mother World Tour was an international concert tour by Pink Floyd. It commenced during September 1970 and ended during October 1971. It marked the first time the band visited countries such as Japan and Australia, making them one of the first European rock bands to do so. Intended to promote their new album Atom Heart Mother, it was occasionally problematic as the band needed to hire local orchestras and choirs on some dates to perform the title piece, it turned to a point where the band decided to play the band version.

Early in 1970, Pink Floyd performed at gigs a piece from their film soundtrack for Michelangelo Antonioni's film Zabriskie Point referred to as "The Violent Sequence". This was the musical basis for "Us and Them", from their The Dark Side of the Moon album. Lacking only the lyrics, it is identical to the final song and is the earliest part of the seminal album to have been performed live. The song "Embryo" was also a part of the live repertoire around this time, but was never to appear on a studio album, until the compilation album Works.

Atom Heart Mother is the fifth studio album by English progressive rock band Pink Floyd, released in 1970 by Harvest and EMI Records in the UK and Harvest and Capitol in the US. It was recorded at Abbey Road Studios, London, England, and reached #1 in the UK, and #55 in the US chart, and went gold in the US in March 1994. A remastered CD was released in 1994 in the UK, and 1995 in the US.

This was the first Pink Floyd album to be specially mixed for 4-channel quadraphonic sound as well as conventional 2-channel stereo. The SQ quadraphonic mix was released on LP in a matrix format compatible with standard stereo record players. There was also a release of the quadraphonic version in the UK in fully discrete 4-channel form on the "Quad-8" format, a 4-channel variant of the stereo 8-track tape cartridge.

The original album cover, designed by art collective Hipgnosis, shows a cow standing in a pasture with no text nor any other clue as to what might be on the record. Some later editions have the title and artist name added to the cover. This concept was the group's reaction to the psychedelic space rock imagery associated with Pink Floyd at the time of the album's release; the band wanted to explore all sorts of music without being limited to a particular image or style of performance. They thus requested that their new album had "something plain" on the cover, which ended up being the image of a cow. Storm Thorgerson, inspired by Andy Warhol's famous "cow-wallpaper," has said that he simply drove out into a rural area near Potters Bar and photographed the first cow he saw. The cow's owner identified her name as "Lulubelle III".^{[dead link]} More cows appear on the back cover, again with no text or titles, and on the inside gatefold. Also, a pink balloon shaped like a cow udder accompanied the album as part of Capitol's marketing strategy campaign. The liner notes in later CD editions give a recipe for Traditional Bedouin Wedding Feast on a card labeled "Breakfast Tips".

George Roger Waters (born 6 September 1943) is an English musician, singer-songwriter and composer. He was a founder member of the progressive rock band Pink Floyd, serving as bassist and co-lead vocalist. Following the departure of bandmate Syd Barrett in 1968, Waters became the band's lyricist, principal songwriter and conceptual leader. The band subsequently achieved worldwide success in the 1970s with the concept albums The Dark Side of the Moon, Wish You Were Here, Animals and The Wall. Although Waters' primary instrument in Pink Floyd was the bass guitar, he also experimented with synthesisers and tape loops and played rhythm guitars in recordings and in concerts. Amid creative differences within the group, Waters left Pink Floyd in 1985 and began a legal battle with the remaining members over their future use of the group's name and material. The dispute was settled out of court in 1987, and nearly eighteen years passed before he performed with Pink Floyd again. It is estimated that as of 2010, the group have sold over 200 million albums worldwide, including 74.5 million units sold in the United States.
