One of our greatest blues artists and composers, and most of us don't even know his name. Listen to the original "The Sky Is Crying" from the composer. (Elmore James wrote the song). He passed away tragically when he was on the verge of the 60's blues revival. Rock and blues owe him a great debt. Elmore James, King of the Slide Guitar: January 27, 1918 - May 24, 1963. He is missed.
