Radiohead is an English alternative rock band from Abingdon, Oxfordshire, formed in 1985. The band consists of Thom Yorke (vocals, guitars, piano), Jonny Greenwood (guitars, keyboards, other instruments), Ed OBrien (guitars, backing vocals), Colin Greenwood (bass, synthesizers) and Phil Selway (drums, percussion).

Radiohead released their first single, Creep, in 1992. The song was initially unsuccessful, but it became a worldwide hit several months after the release of their debut album, Pablo Honey (1993). Radioheads popularity rose in the United Kingdom with the release of their second album, The Bends (1995). Radioheads third album, OK Computer (1997), propelled them to greater international fame. Featuring an expansive sound and themes of modern alienation, OK Computer is often acclaimed as a landmark record of the 1990s.

Kid A (2000) and Amnesiac (2001) marked an evolution in Radioheads musical style, as the group incorporated experimental electronic music, Krautrock, post-punk and jazz influences. Hail to the Thief (2003), a mix of guitar-driven rock, electronics and lyrics inspired by war, was the bands final album for their major record label, EMI. The bands first six albums, released via EMI, had sold more than twenty-five million copies by 2007. Radiohead independently released their seventh album, In Rainbows (2007), originally as a digital download for which customers could set their own price, and later in physical form to critical and chart success. Radiohead released their eighth album, The King of Limbs (2011) in a variety of formats.

Radioheads work has appeared in a large number of listener polls and critics lists. In 2005, Radiohead were ranked number 73 in Rolling Stones list of The Greatest Artists of All Time. While the bands earlier albums were influential on British rock and pop music, musicians in a wide variety of genres have been influenced by their later work.
