OK Computer is the third studio album by English alternative rock band Radiohead. It was first released on 21 May 1997 in Japan, on 16 June by Parlophone in the United Kingdom, and on 1 July by Capitol Records in the United States. Radiohead self-produced the album with producer Nigel Godrich, and recorded the majority of the album in Oxfordshire and Bath, England, between 1996 and early 1997, respectively. With this album, the band made a deliberate attempt to distance themselves from the guitar-oriented and lyrically introspective style of their previous studio album The Bends (1995). OK Computer's abstract lyrics, densely layered sound, and eclectic range of influences laid the groundwork for Radiohead's later and more experimental work.
Upon its delivery to EMI, label representatives generally lowered their sales estimates, deeming the album’s sound “uncommercial” and difficult to market. Nevertheless, OK Computer reached number one on the UK Albums Chart and became the band's highest album entry on the US charts at the time, debuting at number 21 on the US Billboard 200. The album expanded Radiohead's international popularity and received widespread critical acclaim. It initiated a stylistic shift in British rock music, away from the then-ubiquitous genre of Britpop toward melancholic, atmospheric styles of alternative rock that became more prevalent in the next decade. Critics and fans noted the album's lyrics and music depicting a world fraught with rampant consumerism, social alienation, emotional isolation, and political malaise. In this capacity, OK Computer is often interpreted as having prescient insight into the mood of 21st-century life; in subsequent years, it has been cited by listeners, critics and musicians as one of the greatest albums of all time.
OK Computer has sold more than 6 million copies worldwide, and was included by the US Library of Congress in the National Recording Registry in 2015. A remastered version of the album with additional tracks titled OK Computer OKNOTOK 1997 2017 was released on 22 June 2017, to commemorate the album's twentieth anniversary.
