He wasn't really so much a bluesman as he was a songsman. He knew lots and lots of songs of every type. Kinda like Leadbelly. Even as a bluesman he would have been classified as Piedmont which is a mixture of rags, blues, country, religious, cowboy, even Tin Pan Alley. He's part of the region that spawned Blind Blake, Sonny Terry & Brownie McGee and Blind Boy Fuller.
