A few off the top of my head:
Hound Dog Taylor--I love "Gimme Back My Wig"
Robert Cray--more modern, smooth guitar style, 80's crossover hit with "Strong Persuader"
SRV, of course, for an otherworldly blues interpretation
Freddie King (joining Albert and B.B.)-- gotta love a guy who can reference chitlin pizza
Albert Collins' "Cold Snap" is a phenomenal album, in my opinion, with "Dirty Dishes" as my favorite song.
It's a broad universe. Are you more interested in seminal classics? Piano? Guiter? Delta? Chicago? A little more detail might help us target suggestions.
