The soundtrack to Joseph Kosinski's TRON: Legacy was composed by Daft Punk. It was released December 7, 2010, ten days before the movie came out. The soundtrack can be ordered online with a poster depicting Daft Punk in their cameo appearance in the film. Two bonus songs are only available on iTunes, and another can be bought on Amazon. The song "Sunrise Prelude" is only available at Ovi. A Special Edition of the soundtrack is also available, on amazon.ca and amazon.co.uk. It's unknown when it will be available in the US.
The first publically released track was Derezzed, online, in a promotional video with clips from the film (the official Daft Punk music video for the track was released with the soundtrack). The Game Was Changed, around the same time, was posted as a 30-second preview on TRON: Legacy's Facebook page. Five more tracks were previewed at Comic-Con.
TRON: Legacy's director, Joseph Kosinski, said at the 2010 Comic-Con Panel for TRON: Legacy that Daft Punk's score was, "an incredible blend between electronic music, orchestral music, and...an interesting mix between music and sound design." Daft Punk have stated the original TRON soundtrack as an influence.
