I gave her a listen on your advice and i agree it's a good album. She has a nice voice and she's really been practicing her blues guitar. I don't think the purists would like it, but what do they like?
Now let me recommend someone. Harry Manx. He mixes Blues and Indian music. He plays a Mohan veena, a 20-stringed instrument invented by Manx’ Indian mentor Vishwa Mohan Bhatt. It's an acoustic guitar that's been "Indianized."
Start with "Wise or Otherwise" or "Mantras for Madmen". Let me know what you think if you do give him a listen.
