Also, not all of the shows are about black founding fathers. It is important, mainly to see how history that is taught today, isn't history that happened.

But anyway, has anyone heard of the Voices from the Days of Slavery project?

It is a collection of recorded interviews with former slaves done between 1932 and 1975. The audio isn't so great but the transcribed text of the interviews and the recordings are available through the Library of Congress. I've listened to them and read the transcripts. It was actually a project through the Progressive Works Progress Administration.

The interviews aren't widely known, IMHO, because life as a slave wasn't what you may have been taught in your history lessons.
