OK Computer is the third studio album by English rock band Radiohead. It was first released on 21 May 1997 in Japan, on 16 June 1997 in the United Kingdom by Parlophone, and on 1 July 1997 in the United States by Capitol Records. Produced by Nigel Godrich, it was recorded between July 1996 and March 1997, mostly in the historic mansion of St Catherine's Court.
With OK Computer, the band made a deliberate attempt to distance themselves from the guitar-oriented, lyrically introspective style of their previous album The Bends (1995). Critics have noted its lyrics 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. Stylistically, the album initiated a shift in British rock music away from the then-ubiquitous genre of Britpop toward melancholic, atmospheric alternative rock that became more prevalent within the next decade. Its abstract lyrics, densely layered sound, and eclectic range of influences laid the groundwork for the band's later, more experimental work.
Despite lowered sales estimates by the band's record company EMI, who deemed it "uncommercial" and difficult to market, OK Computer debuted at number one on the UK Albums Chart and number 21 on the US Billboard 200. It expanded Radiohead's international popularity and received widespread critical acclaim, and has often been cited as one of the greatest albums of all time. At the 40th Annual Grammy Awards in 1998, it was nominated for the Grammy Award for Album of the Year, ultimately winning the award for Best Alternative Music Album. OK Computer was later certified 2x platinum by the RIAA on 4 May 2006, and later 5x platinum by the BPI on 23 August 2013. A remastered and expanded version titled OK Computer OKNOTOK 1997 2017 was released on 22 June 2017, commemorating the album's twentieth anniversary. Four singles were released from the album: Paranoid Android, Karma Police, Lucky, and No Surprises.
