I do this with the old blues players! People such as Charley Patton, Son House, Blind Blake, Blind Boy Fuller, Sonny Boy Williamson I, Blind Willie Johnson, Robert Johnson, Skip James, Furry Lewis, Miss. John Hurt, Bukka White, etc. and even later greats like Lightnin' Hopkins, Lightnin' Slim, Jimmy Reed.
I think I played When the War Was On (Blind Willie Johnson) about 10 times in a row last time I heard it. Enjoyed it so much! There'll be old time country songs you want to hear the same way. Weems String Band's Greenback Dollar and Davy. A country string band with cello in it, not bowed bass.
