I have been saving this YouTube clip, which my eldest brother brought to my attention, for a while now. As a guitar player (or sorts), I was blown away by the playing skills of Sungha Jung, a mere child from South Korea. Have a look on YouTube for many many other recordings including The Beatles and classical pieces that were added over a number of years, since he was 7!
I chose California Dreamin' as the clip to highlight his skills that include some complex chords, finger plucking, pulling, bending, harmonics and hammer-ons. He is likely to be a huge star one day.
