This kind of blew my mind the first time I saw it. It is really good and pretty much everything this guy does is good. He often involves his wife and little daughter in the videos.
I don't think you'll be disappointed.
EDIT: I sent him a message on youtube telling him he should consider coming here and cross posting his stuff. I don't intend to post any other videos of his unless he decides not to. Really, I only posted it to raise awareness. He is REALLY good at covers and arrangements.
