Halo: Original Soundtrack

Released in 2002, the Halo Original Soundtrack, composed and produced by Martin O'Donnell and Michael Salvatori for the video game Halo: Combat Evolved, is one CD comprising of 26 unique tracks. Some editions do include a bonus DVD with a game trailer for Halo 2 and an E3 Demo Movie and Music Suite. Most of the music from Halo: Combat Evolved is present on the CD, although some songs are remixed and some tracks are intermixed with others in medley form.

According to the information found in the CD booklet, Halo's in-game music is very dynamic and changes as fast as situations change during gameplay. O'Donnell was quoted saying, "Themes, moods and even the duration of these pieces will change and adapt with each player's Halo experience. I took the liberty of remixing and rearranging all the music in order to make listening to the soundtrack more enjoyable."

Trivia

 * Many of these classic Halo songs, such as "On a Pale Horse", "Brothers in Arms", "Perilous Journey", and "Enough Dead Heroes" have returned for the Halo 3 soundtrack, but have been rerecorded.
 * A short instrumental track that is not normally heard in the video game can be found at the end of track 26, "Halo", after 23-24 seconds of silence. The song is known as "The Siege of Madrigal", and is from Bungie's older series of real-time strategy games, Myth. It is a common Halo easter egg.
 * There is one song not on the soundtrack that only plays on Assault of the control room during a battle with a pair of hunters, it has not been remade either.
