Solitary, and anyone who likes guitars really, might appreciate this guy.

He does all kinds of "meets metal" covers that are really great, everything from "My little pony", to movie soundtracks like "Requiem for a Dream" and "nightmare before Christmas", skrillex to Whitney Houston, mortal combat and Tetris. Just, I think this guy is really fun to watch.
