Yorke became disillusioned with the "mythology" of rock music, feeling the genre had "run its course". He had been a DJ and part of a techno band at Exeter University, and following "OK Computer "began to listen almost exclusively to the electronic music of Warp artists such as Aphex Twin and Autechre: "It was refreshing because the music was all structures and had no human voices in it. But I felt just as emotional about it as I'd ever felt about guitar music." He liked the idea of his voice being used as an instrument rather than having a leading role, and wanted to focus on sounds and textures instead of traditional songwriting.
