Good Heavens! That girl has been on this Earth before. Cain't Nobody play like that unless you were there listening to Blind Lester Crawdad back in 1908.
It's so refreshing (and relieving) when you come across a 16 yr old's Youtube Demo and it sounds great, they play even better than they sing, and their influences are up to 70 years old!!
Usually it's young kids in their....uh....formative years who really shouldn't be posting demos just quite yet!
Bravo on this girl, hopefully she does some big stuff, she certainly has the chops.
