OP, thanks for starting this thread.
@mitch2 +1 for Eric Bibb
FWIW, I've been listening lately to Hans Theesink, an acoustic Dutch bluesman now living in Vienna. His renditions of American blues are very good. Occasionally his Dutch accent shows, but he is the real deal as far as I'm concerned.
I'll bemail listening tonight to some of the recommendations from this thread. Have a good day.
