In 1941, the legendary Alan Lomax was sent by the Library of Congress to the Mississippi Delta to record an oral history of the blues. Hauling 500 pounds of equipment powered only by his car battery, Lomax set out across nameless dirt roads to discover the most beautiful and harrowing songs ever sung. This is a spirited recreation of Lomax’s seminal meeting with Bill Henley, a 73-year-old recluse living in the backwoods of Lula, Mississippi.
