This guy is pretty darn good if you ask me. Some pretty fancy stuff going on, he basically nails it.

Seeing stuff like this always makes me wonder, how long did he spend practicing those 2 songs? Or is he just that good at everything he plays? If so, how long has he been playing? I know I can't play any of the songs I know nearly that good, but I also don't focus on any songs, just noodle around with multiple songs...still in my two years of playing, if I focused on just 2 songs, I still don't think I could get play them this well.
