The Radiohead album released in 2000 was Kid A. It arrived on October 2, 2000, as the English band's fourth studio album and marked a dramatic shift away from the guitar-centered alternative rock of OK Computer.
Radiohead recorded Kid A between January 1999 and April 2000 in locations including Paris, Copenhagen, and Oxfordshire, working with producer Nigel Godrich. The album brought in electronic programming, jazz influences, strings, brass, and the ondes Martenot, giving songs such as “Everything in Its Right Place,” “The National Anthem,” and “Idioteque” an unsettled, experimental character.
The album's title can be confused with Amnesiac, which followed in 2001 and contained additional material from the same recording period. Kid A was also unusual in its promotion: Radiohead released no traditional singles from it and used short animations and online material instead. Despite its challenging sound, it debuted at number one in both the UK and the United States.
