The string orchestration for "How to Disappear Completely" was influenced by Polish composer Krzysztof Penderecki. Jonny Greenwood's use of the ondes Martenot on this and several other "Kid A" songs was inspired by Olivier Messiaen, who popularised the instrument and was one of Greenwood's teenage heroes. "Idioteque" samples two computer music pieces, Paul Lansky's "Mild Und Leise" and Arthur Kreiger's "Short Piece". Both samples were taken from "Electronic Music Winners", a 1976 experimental music LP which Jonny Greenwood stumbled upon while the band was working on "Kid A". Yorke also referred to electronic dance music when talking about "Idioteque", and said that the song was "an attempt to capture that exploding beat sound where you're at the club and the PA's so loud, you know it's doing damage".
