This is Washington Phillips. He played an instrument called a "Celestaphone" also known as a "Fretless Zither", a "Phonoharp" or a "Dulceola. (All of which are slightly different, respectively). The instrument he is noted for playing was only made for a few years by two brothers in Ohio. This photo is from 1928. He was a traveling preacher who made magical ethereal music on his rare instrument. Look up his work. He will tell you the gospel straight up while not over looking problems of the church. i.e. "Denomination Blues." It's so beautiful it's almost creepy. It sounds like a man possessed by an angel.
