KG and Ringy are in Mississippi to uncover some of the rarest artifacts of American blues music. First, the guys visit the former homesite of Muddy Waters, one of the most influential blues musicians ever. They hope to discover sweet nectar -- a harmonica reed or old guitar strings -- that can offer insight into his life. Then, they head to a 25,000-acre plantation that hosted blues concerts for thousands of people. KG suddenly hears the sound of juice. Could it be a rare music relic?
