Just back from Memphis and visited BB King's Blues Club 3 times. The first was mid afternoon when nothing was happening but the bar was open. Floor is sticky and the bar has lots of character. (The door staff could have paid more attention to visitors rather than picking her nails but we didn't expect much.)
It is the early evening when things start happening. At 5:30 the 3 piece band Memphis Jones started playing and they are GREAT! Not only are they extremely talented but the leader of the group is a walking encylopedia of music and Memphis history that he despenses in between songs. So good we had to go back again before we left Memphis.
