When I first started reading this thread, I immediately thought: BB King, then Etta James, Roy Buchanan, Janis, surprised me, but I thought Ian, and then Joplin. John Lee Hooker, yes. I was amazed to see Reinhardt and Grappelli, but then "Minor Swing" is my favorite song of theirs, and it's kind of bluesy. I see I have a lot more names to sample from above. Although, I recognize a few more. Thanks.
