Anyone interested in different "covers" of Diablo music should give this a listen, especially the metal heads, it is such an amazing piece played by this guy, he did quite well. Hell, anyone is free to post their covers on Diablo in here if they wish to do so because I'm sure there's a tonne of covers out there of different soundtracks from Diablo.
I would have posted this in the Music forum but since this is a thread dedicated to Diablo covers, I'm sure it'll fit right in here
