OK Computer is the third studio album by the British band Radiohead, originally released in 1997. It is regarded as a landmark in rock, with its combination of guitar rock, electronic textures and themes of alienation, technology and modern life. Well-known tracks include 'Paranoid Android', 'Karma Police', 'No Surprises' and 'Lucky'. This edition, OKNOTOK, gathers the album together with its accompanying B-sides and three previously unreleased songs, including the long-awaited 'Lift'. The whole gives a complete picture of one of the most influential records of the 1990s.
