Forget that carictature rehash regurgitation. Go to the source: get the Yazoo comps. which trace regionalism into depression era music, which is the basis of the northern electric developments. Then go to Chess!
Definitely check out Eilen Jewell (pronounced like feelin'), Letters from Sinners and Strangers. She's not straight blues but a bluesy mix of roots music and she is good. Just read the reviews on Amazon.
Kirk fletcher's new one is great Mitch Kashmar- live at labatt's Ronnie Earl's recent releases are great. if you like nick moss, you will enjoy ronnie. Mitch Wood's latest is fun if you like the New Orlean's blues influence.
Check out Hillstomp, "Darker the Night" or "One Word". Theyre on In Music We Trust label or Fuzzmonster label. Hard to find, might need to go to specialty sites to order but if you like R.L. Burnside, they will float your boat. Also second the Ainsley Lister cd.
