Listen to God don't never change (well, 35 seconds of it)

Willie Johnson
Born 1897 - Brenham, Texas
Died 1945 - Beaumont, Texas

A gruff voiced slide guitarist who sang, mainly, gospel. Apparently a lay preacher, although not too much seems to be known about him. Not (probably) on too many people's top twenty list but I love gruff and I love slide, so I love Blind Willie!
