Soundtrack
In contrast to the movie's predecessors, very few "source" tracks are used in the movie. Aside from Don Davis' score, again collaborating with Juno Reactor, only one external track (by Pale 3) is used.
Although Davis rarely focuses on strong melodies, familiar leitmotifs from earlier in the series reappear. For example, Neo and Trinity's love theme—which briefly surfaces in the two preceding movies—is finally fully expanded into "Trinity Definitely"; the theme from the Zion docks in Reloaded returns as "Men in Metal", and the energetic drumming from the Reloaded tea house fight between Neo and Seraph opens "Tetsujin", as Seraph, Trinity and Morpheus fight off Club Hel's three doormen.
The climactic battle theme, named "Neodämmerung" (in reference to Wagner's Götterdämmerung), features a choir singing extracts (shlokas) from the Upanishads. The chorus can be roughly translated from Sanskrit as follows: "lead us from untruth to truth, lead us from darkness to light, lead us from death to immortality, peace peace peace". The extracts were brought to Davis by the Wachowski brothers when he informed them that it would be wasteful for such a large choir to be singing simple "ooh"s and "aah"s (according to the DVD commentary, Davis felt that the dramatic impact of the piece would be lost if the choir was to sing 'This is the one, see what he can do' in plain English). These extracts return in the denouement of the movie, and in Navras, the track that plays over the closing credits (which may be considered a loose remix of "Neodämmerung").
