I love Sungha Jung!!! I have followed this kid for several years via YouTube and he is nothing sort of extraordinary. I believe he started guitar at 10 and the rest as they say, is history. A prodigy for sure. He does some lovely duets with Trace Bundy (whom I also think is an amazing and innovative fingerstyle guitarist), among others that are out of sight.
Ukulele came after his initial foray into guitar, but clearly he is as gifted in that arena as the other.
Check out his interpretation of Ennio Morricone's New Cinema Paradiso and Sting's Saint Agnes and the Burning Train on his channel--just a couple of my favs. Also, a moving interpretation of Yiruma's The River Flows in You on guitarlele. He is a prolific video poster...so plenty to choose from.
So much beauty from one person!!
