Check out his autobiography. "Man of Constant Sorrow". Interesting read. As a former bluegrass mandolinist and singer, ralph was one of my vocal heroes. So much soul.Saw him perform live when he was 85 and he blew me away.
At our weekly Monday night Hootenanny in Urbana this week one local performer played/sang a set of RS songs with a pickup band of appreciative local musicians.
Lots of applause...
I enjoy hillbilly blues as well as honky-tonk music, jug band music, traditional blues, urban blues, jump and swing, country, rock, folk, and even some jazz if it has an accessible chord structure.
