Amnesiac is the fifth studio album by the English rock band Radiohead. It was produced by Nigel Godrich and released on 5 June 2001 through Parlophone. Recorded in the same sessions as previous album Kid A (2000), Amnesiac incorporates similar influences of electronic music, classical music, jazz and krautrock. Its lyrics and artwork explore themes of memory and reincarnation influenced by ancient Greek and Egyptian mythology. Bassist Colin Greenwood described Amnesiac as having "more traditional Radiohead-type songs together with more experimental, non-lyrical based instrumental-type stuff as well." Singer Thom Yorke described it as "another take on Kid A, a form of explanation."
