Radiohead are an English rock band. Formed in Oxfordshire in 1986, the band consists of Thom Yorke (lead vocals, rhythm guitar, piano, electronics), Jonny Greenwood (lead guitar, other instruments), Ed O'Brien (guitar, backing vocals), Colin Greenwood (bass guitar, synthesisers) and Phil Selway (drums, percussion).

Radiohead released their first single, "Creep", in 1992, followed by their debut album Pablo Honey (1993). Though it was initially unsuccessful, the song became a worldwide hit by the time it was reissued a year later. Radiohead's popularity in the United Kingdom increased with their second album, The Bends (1995). The band's dense, textured guitar atmospheres and Thom Yorke's expressive falsetto singing were warmly received by critics and fans. Radiohead's third album, OK Computer (1997), propelled them to greater attention. Featuring an expansive sound and themes of modern alienation, it was acclaimed worldwide, often being named a landmark record of the 1990s.

The band's next recordings, Kid A (2000) and Amnesiac (2001), saw Radiohead reach their peak of global popularity even as their music divided fans and critics. The period marked a change in the band's style, with influences including experimental electronic music as well as Krautrock and jazz. Radiohead's shift away from standard rock songwriting also resulted in greater flexibility, with each member playing a wider range of instruments in the studio and at live concerts. The band's sixth album, Hail to the Thief (2003), was seen to blend styles from throughout their career, mixing guitar-driven rock, electronic influences and contemporary lyrics.

Radiohead subsequently left their record label EMI, and released their seventh album, In Rainbows (2007), through their own website as a digital download for which customers could select their own price. Radiohead plan to release In Rainbows as a "discbox", as well as on a standard CD in December 2007, through XL Recordings and TBD Records. The band plan to embark on a world tour, beginning in late spring 2008.
