Amnesiac is the fifth studio album by the English rock band Radiohead, released on 30 May 2001 by EMI subsidiaries Parlophone and Capitol Records. It was recorded with the producer Nigel Godrich in the same sessions as Radiohead's previous album Kid A (2000); Radiohead split the work in two as they felt it was too dense for a double album. As with Kid A, Amnesiac incorporates influences from electronic music, 20th-century classical music, jazz and krautrock. The final track, "Life in a Glasshouse", is a collaboration with the jazz trumpeter Humphrey Lyttelton and his band.
