Impressive Cover Of Pixies' 'Where Is My Mind?'

I first saw this video a couple of weeks ago and was blown away.  It's from a British beatboxer that goes by the name of "Petebox".  He's been on the scene in the UK for a few years, mostly doing covers and live drum 'n' bass demonstrations.  It appears as though he's starting to branch out and try his hand at some covers with an acoustic guitar.  He's using a loop pedal that can be picked up used for anywhere from $100 to $150 at your local Guitar Center.  My brain can't even think on this many layers simultaneously, musically speaking.
