Halo 3: Original Soundtrack

Released in 2007, the Halo 3: Original Soundtrack, composed and produced by Martin O'Donnell and Michael Salvatori, is a two-disc set much like the Halo 2: Original Soundtrack. The Halo 3: Original Soundtrack was released in one set rather than separate volumes like its predecessor. The Halo 2 OST deviated from the Halo 2: Original Soundtrack, and reverted back to the structure used in the Halo: Original Soundtrack. Comprised of melodies, chants, and trumpets, the Halo 3: Original Soundtrack is broken up into chapters which correspond to in-game levels.

Disc one is broken up into into the beginning levels of the game, and splits at about midway though the campaign. Consisting of 15 songs of longer length, disc one runs slightly longer than disc two. Consequently, disc two is broken up into the latter levels of the game, while including four bonus tracks. One of these bonus tracks is the music present in the E3 2006 Trailer with the exception of the dialog. Composed of music entirely in-game, from start to finish, the story of Halo 3 is played out in musical form.

Trivia

 * To hear more about this album listen to the September 20th Bungie Podcast.
 * When played in reverse, Black Tower on Disc 2 plays a cryptic message from the Gravemind, different than the one heard on the Halo 2: Original Soundtrack. . The quotes reflect several lines from T.S. Elliot's poem, The Hollow Men ; which is the original source of Cortana's famous words; "This is the way the world ends."
