I've been playing ukulele for about 2 years and I love it and I'm okay for my experience level. Not great but okay.
But this little effer! He's no more than 10 years old and he's killin' it! Everything he's doing is hard and super-impressive and he's got this grin on his face like, "Yeah bro...this is easy."
Seriously though, good for him! Check out him playing "Bad Guy".
