Blake Robinson has put together a "synthetic orchestration" of the original Wing Commander theme music. The track retains the original's character while adding a nice richness to it. Blake has done a number of reorchestrations for other game series, such as Gears of War and Resident Evil. You can listen to the new WC creation below or grab an mp3 at Soundcloud here.
Thanks to MannPower for spotting this one!
