Composer Don Davis's official website has just released some details of the upcoming soundtrack release to The Matrix Revolutions:
The Maverick Records soundtrack to The Matrix Revolutions will be released on November 4, 2003, one day before the movie opens, and will have over an hour of music on it, including the song "In My Head" by Pale 3, which plays in the Merovingian's Hell Club (3:46), two cues that feature Don Davis' collaboration with Juno Reactor, a 9 minute end credit re-mix of Don Davis' "Super Burly Brawl" music by Juno Reactor, and 45 minutes of orchestral underscore by Don Davis. Apparently no rock bands were inspired by this movie.
