Apparently he's an attorney in Utah who just plays at this pizza place once a month. He's got 84 covers on youtube and most of them I like better than the originals:

Holy CRAP! That dude ROCKS!

Dude rips. I would be at that pizza place all the time.

Glad that somebody else agree's. I've been listening to this dude constantly for the last week. I think this one's my favorite:

Awesome, talented as hell. After this was posted checked him out on youtube and was going to have my brother in law who lives in Salt Lacke City go watch him at that pizzeria but all of his shows had been cancelled because his one year old son was diagnosed with a malignant brain tumor and he is on hiatus.
