He's pretty good... in ten years' time, if he develops some charisma and the ability to look at his audience not always at his fingers, and with a little luck a decent singing voice and a good backing band, he'll be a guitarist to watch... A rock band I used to go and watch occasionally, now sadly defunct, used to do a fully rocked-up Bach Toccata & Fugue in D minor as an encore, that was a cracker!
If you prefer a guitarist who's only ever plugged in enough to project an accoustic guitar to the back of a big auditorium, try some of Antonio Forcionne's work, the guy's just incredible. Unfortunately there's no clips of him on youtube and I can't really post any or I'll be in trouble with the copyright people... and with Nils, which would be infinitely scarier...
