"Halo Trilogy," the complete soundtracks composed and produced by the award-winning team of Martin O'Donnell and Michael Salvatori for Microsoft's top-selling "Halo" video game franchise, will be released tomorrow (Dec. 2) as a five-disc collectible set by Nile Rodgers' Sumthing Else Music Works label.

The bonus "Halo Wars" DVD includes four preview tracks in 5.1 surround sound for the highly anticipated sequel game, due from Microsoft Games in early 2009 exclusively for the Xbox and Xbox 360 platforms. The Halo franchise has sold close to 25 million games worldwide, according to Microsoft.

Sumthing Else's Web site is also selling the soundtracks as digital downloads.

The DVD offers a behind-the-scenes look at the "Halo Wars" recording sessions held at Ensemble Studios, under the audio direction of composer Stephen Rippy, with musicians from the Seattle Symphony, Dallas Symphony and Prague Symphony orchestras. Also included is the "Five Long Years" opening cinematic of the "Halo Wars" campaign.

"Our label has done all the prior Halo soundtracks as Microsoft's licensing partner and we'll have a complete 'Halo Wars' soundtrack just before the game release next year to piggyback the publicity," Sumthing Else president Andy Uterano tells Billboard.
