Blind Alfred Reed would be considered, I believe, an "old time" or "hillbilly" musician rather than a blues musician, but he did record "Black and Blue Blues". He was first recorded at the "Birth of Country" 1927 Bristol sessions (along with the Carter Family and Jimmie Rogers) and is probably best known for "How Can a Poor Man Stand Such Times and Live".
