I'm looking for the name of the singer who accomponies Lead Belly on "Outshine the Sun" & "Nobody Knows the Trouble I've Seen". These versions are on the album "Nobody Knows the Trouble I've Seen" released on Rounder Records (Also known as The Library of Congress Recordings Vol. 5) Any info on where I might be able to find more recordings by this singer would also be welcome. Thank you in advance.
