I've met big bro Jimmie quite a few time too and I admire his playing, its diametrically opposed to Stevie's playing in terms of blues but I really dig his vibe too.
As far as a pure blues player I can't get past BB, that tone, that voice,...he IS the KING.
Can you imagine being in that club when Stevie played on stage with Albert King when it's a well known fact that Albert didn't like ANY other blues player. Man, talk about huge balls...
