Sumthing Else Music Works, Inc. and Microsoft Game Studios have announced the launch of HALO3OST.com, an website dedicated to the Halo 3 Original Soundtrack which will be released on November 20th to US retail outlets through Nile Rodgers’ Sumthing Else Music Works label and via digital download at Sumthing Digital. The soundtrack comes in a 2-CD set featuring the new symphonic compositions by Martin O'Donnell and Michael Salvatori, the award-winning composers behind the best-selling Halo: Combat Evolved, Halo 2 Volume One and Halo 2 Volume Two soundtracks. In addition to new original tracks written for the Halo 3 video game, the Halo 3 Original Soundtrack also includes new arrangements of the game’s musical themes that Bungie’s audio director and composer Martin O’Donnell recorded with a full live orchestra and chorus. The 2-CD set amounts to two hours of original music from the game Halo 3.
