I've been listening to Gavin Dunne for years. I first discovered him when he joined the Escapist a few years ago (and he's unfortunately no longer with them).
He creates entirely original songs for video games with lyrics. What makes him different from Brentalfloss is that he doesn't remix existing tracks; instead, he makes his own original compositions. Check out his archive (http://www.escapistmagazine.com/videos/view/miracle-of-sound) at the Escapist.
I'm creating a thread for him now because he just released his latest album, METAL UP, for free on his YouTube account. Check it out here. (https://www.youtube.com/watch?v=YKF27GAsxJM)
