Halo 2: Original Soundtrack

The Halo 2: Original Soundtrack was composed and produced by Martin O'Donnell and Michael Salvatori, with a few tracks by Incubus. While the Halo: Original Soundtrack was released in a one format, the Halo 2: Original Soundtrack was split into two volumes, which were released almost two years apart. Volume 1 was released on November 9th, 2004 and Volume 2 was released on April 25th, 2006. Rather than keep the medley form from the Halo: Original Soundtrack, the Halo 2: Original Soundtrack focused more on suites with different chapters, similar to movements in a symphony. Unlike the Halo: Original Soundtrack, the Halo 2: Original Soundtrack focuses more on heavy guitar riffs and beats as evident in the re-designed Halo Theme- Mjolnir Mix. As such, O'Donnell brought in several bands and guitarists (such as Incubus and Breaking Benjamin) to help compose the songs.

Volume 1 of the soundtrack differs greatly from Volume 2 in the presentation and form of the songs. While Volume 1 is made up in a "movement" form, Volume 2 focuses heavily on suites. As stated on the Volume 2 inlay card, Martin O'Donnell details why he chose to use this structure: "I decided to use a "suite" structure that corresponds to the chapters within the game. In a sense, by listening to this soundtrack, you will hear the musical representation of the story of Halo 2."

Trivia

 * Volume 1 also included an excerpt of the Covenant Writ of Union.
 * Volume 2 also included an excerpt of the Covenant Ratification Parley.
 * When played in reverse, Mausoleum Suite on Volume 2 plays a cryptic message from what is thought to be the Gravemind, but could in truth be many people/AI.
 * There are five tracks not included in either of the two Halo 2 OST's, and can only be heard during gameplay, these are:
 * Metropolis (Bridge) - This is an altered version of the MJOLNIR Mix track, focusing on the instrumental side.
 * Metropolis (Finale) - Another altered version of the MJOLNIR Mix, this one, focusing on the guitar.
 * Delta Halo (Landing) - This track somehow resembles the track In Amber Clad, yet it is shorter than it's counterpart.
 * Quarantine Zone (Drumrun) - As it's name implies, this track is focused on the drum section.
 * Cairo Station (Armory and Commons B-01)(no one has ripped this track so far) - A rather melancholy orchestral piece, heard after the Master Gunnery Sergeant is killed.
