Prelude, also known as 2001, is a 1972 album of Brazilian keyboardist Eumir Deodato. With the signature track “Also Sprach Zarathustra (2001)” (an arrangement of the theme from 2001: A Space Odyssey), Prelude would be the biggest hit Deodato and CTI Records ever had.
The album features guitarist John Tropea on three tracks, bassists Ron Carter and Stanley Clarke, and Billy Cobham on drums.
The funk-influenced version of the “Introduction” from Richard Strauss’s Also sprach Zarathustra, entitled “Also Sprach Zarathustra (2001)”, won the 1974 Grammy Award for Best Pop Instrumental Performance and went to No. 2 in the pop charts in the US, No. 3 in Canada, and No. 7 in the UK.
