Cut a rug on the red carpet with two filmmakers who always put music in a starring role. Director of Pink Flamingos, Hairspray, Cry-Baby and many more, John Waters joins us to talk about his obsession with 1950’s R&B and rock. Documentarian Les Blank recalls working with American Routes marquee names Lightnin’ Hopkins, Clifton Chenier and Dizzy Gillespie.

Working class, self-styled and always opinionated, the late King of Bluegrass Jimmy Martin talks guitar-picking, hunting dogs and the Opry. And singer of songs Percy Sledge recalls going from hospital orderly to Atlantic Records soul singer with “When a Man Loves a Woman.”

Singer-songwriter Loudon Wainwright III walks us through his long career that began in the ’60s folk scene. Also, a live set from the South Carolina Blues Doctor Drink Small.
