Thanks for all the suggestions and sorry for the mis-spelling of the header, obviously it should of read, "Blues...". My wife and I did play a few seconds of a Eric Bibb disc at Barnes & Noble, but when I switched to Keb Mo, Slow Down, it was a no contest, we purchased another KM disc. Maybe it was just the Eric Bibb CD we tried. I did notice we liked the Slow Down CD better than a couple other KM CD's.
I will jot down some of the others and look into them when I get a chance.
