I'd really like some pointers towards some of the less well-known but great blues players. I'm aware of people like Muddy Waters, Mississippi John Hurt, Blind Lemon Jefferson, etc, and the "rock" blues players of the 60s and 70s who went on to fame and fortune as "global" names, but I have a strong feeling that there's a whole wealth of blues out there that I don't have a clue about.
