There's no doubt Radiohead is one of the biggest rock groups in the world. Formed in England in 1985, the band gained worldwide exposure after their hit debut single "Creep". Radiohead's popularity rose exponentially, and they quickly released a second album in 1995. Their third album, Alienation, propelled them to international fame with an expensive sound and themes of modern alienation (something that was closely attributed to 90s rock). Since their success, they've released a total of 9 studio albums, with multiple singles, EPs, and music videos to accompany. In 2009, Rolling Stone readers voted Radiohead the second-best artist in the 2000s.
