I found a website called Voices from the Days of Slavery that has digital recordings of former slaves. Right now I'm listening to the interview of a George Johnson from Mound Bayou, Mississippi back in Sept. 1941. Very interesting and somewhat eerie for me and only because for some reason I never imagined that someone would have thought to make a phonograph oral history recording. Hearing the cracking and skipping of a record. It was really great to hear this aspect of American history.
