Here's a video of a high school band playing their version of the Halo theme song. It sounds pretty good and features a violin, electric guitar, and drums. This version of the video is in their 'studio' AKA the living room. There are two additional versions in the related section on the host site where they play the Halo theme song at their high school talent show. The sound is much better in this video but lacks the stage effects. It reminds me of TheMetalBandWhichShallNotBeNamed which partnered with a symphony. I wonder how Bungie feels about fanmusic. Will they pull a TheMetalBandWhichShallNotBeNamed or let it be?
