hi, Radiohead are an English rock band
Thats right from Abingdon, Oxfordshire. Formed around 1985.
YEs, The band consists of Thom Yorke, brothers Jonny Greenwood
Since 1994 they've worked with the same producer Nigel Godrich.
Radiohead released their debut single "Creep" in 1992. It became a worldwide hit after the release of their debut album, Pablo Honey (1993)
I love that album and especially that song. In the Uk, it was their second album "The Bend" that increased their popularity. 
Good,Radiohead's sixth album, Hail to the Thief (2003), mixed rock and electronic music with lyrics inspired by the War on Terror,
Thom Yorke wrote many of the lyrics for that album in response to the war on terror.
Oh okay, Most of the albums are hit. Radiohead had sold more than 30 million albums worldwide by 2011
Thats a lot of albums. In my opinion they are one of the best bands ever and a classic group.
