I never considered SRV. I only know what was on the radio, but that never got me interested to follow up. I think his music would be cool background or live music, but it's not in my wheelhouse to listen to.
I thought of CDG, but dismissed him pretty quickly. Warning and O:M are landmark albums, and I have 2 guitarists that died young after only making 2 and 3 albums, but the guitars never really stood out to me in QR. If CDG was the lone guitarist in QR, then maybe, but I'm not sure where CDG stops and Wilton starts. To me, what appealed to me about QR was Tate and Rockenfield.
I'll be surprised if I have more than 6 names on this list.
