These audio files are just a few examples of the 100's of recordings available as part of *** The John and Ruby Lomax 1939 Southern States Recording Trip *** At the time these were downloaded (April 2014) it was possible to retrieve these MP3s from this fairly low-tech site: http://memory.loc.gov/ammem/lohtml/lomaxbibAudios1.html These recordings may have moved as the Library of Congress is upgrading its archives.
