The release for Halo 3: ODST is quickly creeping up on us, but you may have forgotten about the soundtrack. Halo has one of the most recognizable themes in gaming today, and certainly one of the most celebrated. Bungie’s new game comes with more mood-defining melodies from composer Martin O’Donnell, the guy responsible for the entire series.

“I’m happy to be able to share all new compositions and recordings created for Halo 3: ODST,” O’Donnell said. “The music reflects the new mood, new heroes, and new story of the game. I worked with the Northwest Sinfonia for the orchestral recordings and also added some nice alto sax solos and some new guitar solos. The piano sneaks back in again a few times too, but I can’t seem to help that.”

The soundtrack will release on the 22nd along with the game.
