Atom Heart Mother is the fifth studio album by the English progressive rock band Pink Floyd. It was released by Harvest on 2 October 1970 in the UK, and by Capitol on 10 October 1970 in the US. It was recorded at Abbey Road Studios in London, England, and was the band's first album to reach number 1 in the UK, while it reached number 55 in the US, eventually going gold there. A remastered CD was released in 1994 in the UK and the United States, and again in 2011. Ron Geesin, who had already influenced and collaborated with Roger Waters, contributed to the title track and received a then-rare outside songwriting credit.
