Amazing, check out their influence
My dad had a lot of this collection on tape, and we listened to it all the time. I'm compiling a blues CD to give to him on Father's Day, and discovered that a lot of these songs are originally attributed to "Blind Willie Johnson". Check out his album "Thank God I'm Satisfied" on eMusic, and enjoy. I love the purity that comes from the early recording quality. Thankfully, every pop and crackle are preserved. Amen.
