Part three of Rockstar's GTA: Chinatown Wars PSP audio preview is now available.

"Part three of our music reveals from the exclusive soundtrack of Grand Theft Auto: Chinatown Wars for PSP delivers the genre-leaping instrumental rock sounds of Tortoise.

"Often referred to as 'post-rock', this Chicago-based outfit was one of the very first bands to fearlessly incorporate hip-hop, techno, dub and drum'n'bass into modern guitar-based rock'n'roll in the late 1980's, earning them worldwide acclaim. Influential to this day, Tortoise's most recent album is the critically acclaimed Beacons of Ancestorship."
