He is best known for composing Grabbag (Duke Nukem Theme), now one of the most recognizable PC game themes to date. He also wrote the soundtracks to "Rise of the Triad," "Shadow Warrior" (the original 1997 release), and "Stargunner." He has since released four albums: "Calibrations," "Derivations," "Duke Nukem Tank Tracks," and "Lady Tygress' Suite and Other Commissions." Read more on Last.fm
