Amnesiac is the fifth studio album by English rock band Radiohead. It was first released on 4 June 2001 in the United Kingdom by Parlophone and a day later in the United States by Capitol Records. Much of its material was recorded during the same sessions for the band's previous album Kid A (2000), incorporating similar influences of krautrock and electronica. Its lyrics and artwork explore themes of memory, with influences from ancient Greek and Egyptian mythology.
