Alex, in my young days, I traveled from one blues joint to another; consequently, my familiarity with the blues is from live music, as opposed to records, as in jazz, and the only famous name I can recall is Albert King.
At that time I never had one serious thought about the music, I was just out to have a good time, and now I have to reflect back to those times in order to put the music in some kind of perspective. When I reflect back to what I heard at that time, the blues I heard was either Delta, or New Orleans based, meaning originated from one of those two places, and I make that statement founded on what Rok, the blues expert has said about the music.
Although I liked "Tiny Grimes" I was unable to put his guitar into any kind of perspective, it sounded original to me; but what's all important is whether or not I liked it, and I did.
Enjoy the music.
