Radiohead are an English alternative rock band from Oxfordshire. The band is composed 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). Since 1993, Radiohead have released seven studio albums. The band have sold over 25 million albums as of 2007.

Radiohead released their first single, "Creep", in 1992. Their debut album, Pablo Honey, followed in 1993. "Creep" was initially unsuccessful, but the song became a worldwide hit when reissued a year later, and the band were almost branded as one hit wonders. Radiohead's popularity in the United Kingdom increased with the release of their second album, The Bends (1995). The band's textured guitar atmospheres and Yorke's falsetto singing were warmly received by critics and fans. Radiohead's third album, OK Computer (1997), propelled the band to greater fame worldwide. Featuring an expansive sound and themes of alienation from the modern world, OK Computer has often been acclaimed as a landmark record of the 1990s.

The release of Kid A (2000) and Amnesiac (2001) saw Radiohead reach the peak of their popularity, although the albums divided critical opinion. This period marked a change in Radiohead's musical style, with their incorporation of avant-garde electronic music, Krautrock and jazz influences. Hail to the Thief (2003), which mixed guitar-driven rock with electronics and contemporary lyrics, was the band's final album for their record label, EMI. Radiohead's seventh album, In Rainbows (2007), was first released independently as a digital download for which customers selected their own price, later meeting with critical and chart success.
