Has anyone heard of guitarist Blind Gary?

I just watched a documentary on cable about three guitarist and their influences. They were Jack White, Jimmy Page, and 'Edge' from U2.

They talked about and showed some "angry" 1930s blues and in paricular a guitarist named "Blind Gary" seemed very cool. I'd love to know more about him, but I can't find anything anywhere. Has anyone here ever heard of this guy, or actually heard him....and what's your take?

Thanks,
