Sumthing Else Music Works announced that the Halo 3 Original Soundtrack is now available at U.S. retailers and as a digital download from the Sumthing Else Digital site, features all the music from the Xbox 360 game that released on November 20.

The two CD set, composed by Martin O'Donnell and Michael Salvatori (the award-winning musicians behind Halo: Combat Evolved, Halo 2 Volume One and Halo 2 Volume Two), the Halo 3 Original Soundtrack features two hours of recording along with new arrangements of the game's musical themes with a live orchestra and chorus.

With over 20 million copes sold, the Halo series is now a staple in the video game universe. We fully expect to see everything from exotic imports to street legal racers to minivans pumping Halo 3 tunes out to cheer up those in traffic.
