Someone on another forum recommended CHARO for this genre.
If you can keep the Cootchie-Cootchie image out of your mind and find an album that focuses on her guitar-playing, you might give it a listen.
She was on the Today Show recently, so there must be a new CD available?? It's kind of a shock to see her play seriously---like when Jim Nabors (Gomer Pyle) or Jason Alexander (Seinfeld's George) would set aside their comedy and sing.
