Kid A is the fourth studio album by the English rock band Radiohead, released on 2 October 2000 by Parlophone. Burnt out after promoting Radiohead's 1997 album OK Computer, songwriter Thom Yorke envisioned a radical change in direction. Radiohead replaced their rock sound with synthesisers, drum machines, the ondes Martenot, string orchestras and brass instruments, incorporating influences from genres such as electronic music, krautrock, jazz, and 20th-century classical music. They recorded Kid A with OK Computer producer Nigel Godrich in Paris, Copenhagen, Gloucestershire and their hometown Oxford, England. The sessions produced over 20 tracks; Radiohead saved many of them for their subsequent album, Amnesiac, released the following year.
