This is AMAZING! This kid is playing an arrangement of Pachelbel's Canon in D, and it will ROCK YOUR FACE. The kid's probably 13 or so, and boy, does he have talent! Only a few extremely minor flubs, but good GAWD, I wish I could play like that. Listen to it LOOOOOUUUUUD!!!
EDIT: OK, the kids name is Lim Jeong Hyun (funtwo), and he's actually 25. The interesting thing is, he's doing an arrangement by a guy named JerryC (Jerry Chang), who ALSO has a video on YouTube. The two performances are very similar, but you can definitely tell a difference. Funtwo's is a little better technically (the runs and arpeggios are a bit cleaner), but JerryC's has a little more "heart". Personally, I like funtwo's a little better, but they're both outstanding. Here's the original. Enjoy!
