Radiohead - Pyramid Song (2A)

Amnesiac is the fifth studio album by the English alternative rock band Radiohead. It was released on 4 June 2001 in the United Kingdom, debuting at #1 on the UK charts and #2 on the Billboard Top 200. Amnesiac featured more audible guitar than its direct predecessor Kid A, and unlike that album, it spun off several singles. Like Kid A, it synthesised influences of electronic music, ambient music, classical music, and jazz.
