Thom Yorke in the context of "R.E.M."

Radiohead are an English rock band formed in Abingdon, Oxfordshire, in 1985. The band members are Thom Yorke (vocals, guitar, keyboards); the brothers Jonny Greenwood (guitar, keyboards, other instruments) and Colin Greenwood (bass); Ed O'Brien (guitar, backing vocals); and Philip Selway (drums). They have worked with the producer Nigel Godrich and the cover artist Stanley Donwood since 1994. Radiohead's experimental approach is credited with advancing the sound of alternative rock.

Radiohead signed to EMI in 1991 and released their debut album, Pablo Honey, in 1993. Their debut single, "Creep", was a worldwide hit, and their popularity and critical standing rose with The Bends in 1995. Their third album, OK Computer (1997), is acclaimed as a landmark record and one of the greatest albums in popular music, with complex production and themes of modern alienation. Their fourth album, Kid A (2000), marked a dramatic change in style, incorporating influences from electronic music, jazz, classical music and krautrock. Though Kid A divided listeners, it was later named the best album of the decade by multiple outlets. It was followed by Amnesiac (2001), recorded in the same sessions. Radiohead's final album for EMI, Hail to the Thief (2003), blended rock and electronic music, with lyrics addressing the war on terror.

William Emmanuel Bevan, known by his recording alias Burial, is a British electronic musician from South London. Initially anonymous, Burial became the first artist signed to Kode9's electronic label Hyperdub in 2005. He won acclaim the following year for his self-titled debut album, an influential release in the UK's dubstep scene which showcased a dark, emotive take on UK rave music styles such as UK garage and 2-step; it was named the album of the year by The Wire. Burial's second album, Untrue, was released to further critical acclaim in 2007, and recognised as a landmark work of electronic music.

In 2008, Bevan's identity was revealed by The Independent and confirmed by Hyperdub. In the following years, he went on to collaborate with artists such as Four Tet, Massive Attack, Thom Yorke, Zomby, and The Bug, in addition to releasing a series of long-form EPs such as Kindred (2012), Truant / Rough Sleeper (2012), and Rival Dealer (2013); most of these releases were later compiled on the 2019 compilation Tunes 2011–2019. He has remained reclusive, giving few interviews and avoiding public appearances. AllMusic described him as "one of the most acclaimed, influential, and enigmatic electronic musicians of the early 21st century".

Edward John O'Brien (born 15 April 1968) is an English guitarist, songwriter, and member of the rock band Radiohead. He releases solo music under the name EOB.

O'Brien attended Abingdon School in Oxfordshire, England, where he formed Radiohead with schoolmates. O'Brien said his role was to "service the songs" and support the songwriter, Thom Yorke. He creates ambient sounds and textures using effects, sustain units and the EBow, and provides backing vocals.

Nigel Timothy Godrich (born 28 February 1971) is an English record producer, recording engineer and musician. He has worked with acts including Radiohead, Travis, Beck, Air, Paul McCartney, U2, R.E.M., Pavement, Roger Waters, Arcade Fire and Idles.

Early in his career, Godrich worked as the house engineer at RAK Studios, London, under the producer John Leckie. He first worked with Radiohead while engineering their second album, The Bends (1995), at RAK. Radiohead hired him to produce OK Computer (1997), which was a major success and brought him attention from major artists. He has produced all of Radiohead's albums since, along with several other projects with the Radiohead members Thom Yorke and Jonny Greenwood. Godrich won the Grammy Award for Best Engineered Non-Classical Album for the 2003 Radiohead album Hail to the Thief.

Dan Rickwood (born 29 October 1968), known professionally as Stanley Donwood, is an English artist and writer. Since 1994, he has created all the artwork for the rock band Radiohead with their singer, Thom Yorke, plus many of Yorke's other projects, including Atoms for Peace and the Smile. In 2002, the pair won a Grammy Award for Best Recording Package for the Radiohead album Amnesiac. Donwood also creates artwork for Glastonbury Festival, and has published books of short stories and a memoir.

Kid A is the fourth studio album by the English rock band Radiohead, released on 2 October 2000 by Parlophone. It was recorded with their producer, Nigel Godrich, in Paris, Copenhagen, Gloucestershire and Oxfordshire. Departing from their earlier sound, Radiohead incorporated influences from electronic music, krautrock, jazz and 20th-century classical music, with a wider range of instruments and effects. The singer, Thom Yorke, wrote abstract lyrics, cutting up phrases and assembling them at random.

In a departure from industry practice, Radiohead released no singles and conducted few interviews and photoshoots. Instead, they released short animations and became one of the first major acts to use the internet for promotion. Bootlegs of early performances were shared on filesharing services, and Kid A was leaked before release. In 2000, Radiohead toured Europe in a custom-built tent without corporate sponsors.

Hail to the Thief is the sixth studio album by the English rock band Radiohead. It was released on 9 June 2003 through Parlophone internationally, and through Capitol Records in the United States on 10 June. It was the last album released under Radiohead's record contract with EMI, the parent company of Parlophone and Capitol.

After transitioning to a more electronic style on their albums Kid A (2000) and Amnesiac (2001), which were recorded through protracted studio experimentation, Radiohead sought to work more spontaneously, combining electronic and rock music. They recorded most of Hail to the Thief in two weeks in Los Angeles with their longtime producer, Nigel Godrich, focusing on live takes rather than overdubs. The singer, Thom Yorke, wrote lyrics in response to the election of the US president George W. Bush and the unfolding war on terror. He took phrases from political discourse and combined them with elements from fairy tales and children's literature. The title is a play on the American presidential anthem, "Hail to the Chief".
