This Washington Post story introduces the Library of Congress's release on its website of recordings of former slaves, "Voices from the Days of Slavery: Former Slaves Tell Their Stories". Here are about 7 hours of recorded oral history interviews, done after 1930 by Zora Neal Hurston, John Lomax, and others. The sound quality can be difficult, but you can bring up transcripts of the interviews to follow as you listen to them. How can you miss hearing an 80 year old former slave sing"My God is a Rock in a Weary Land"?
