OK Computer is the third studio album by English rock band Radiohead, released on 21 May 1997 on EMI subsidiaries Parlophone and Capitol Records. Radiohead self-produced the album with Nigel Godrich, an arrangement they have used for their subsequent albums. The band distanced themselves from the guitar-centred, lyrically introspective style of their previous album, The Bends. OK Computer’s abstract lyrics, densely layered sound and eclectic influences laid the groundwork for Radiohead’s later, more experimental work. The album depicts a world fraught with rampant consumerism, social alienation, emotional isolation and political malaise; in this capacity, OK Computer has been said to have prescient insight into the mood of 21st-century life. The band used unconventional production techniques, including natural reverberation through recording on a staircase, and no audio separation. Strings were recorded at Abbey Road Studios in London. Guitarist Ed O’Brien estimated that 80 per cent of the album was recorded live.
