I was going to go with friends down to Clarksdale, MS, for several weeks one summer, and they were from there, had recorded there, knew everyone, and were going to take his Square White Self down there to add some soul to my bones. It didn't work out, and I've regretted it ever since.
Follow blues, rock and roll, country and country blues, gospel and jazz backwards in time and they all grew from a common root: Here you can hear it in spades. She sings this more country blues, almost folk-like. Rev this up and/or darken it, it's blues or rock and roll. Turn the changes inside out, it's jazz.

THIS is the well. Upside down/left handed, and she can pick, and notice with the guitar strung normally for a right-hander, when she finger picks her thumb is playing the high notes and her fingers the low ones. Backwards ! Plus an included guitar lesson at first. A priceless treasure.
