We go to Miami to enjoy highlights from the 21st annual Afro Roots Fest at the the North Beach Bandshell. Co-headliners are the sublime griot singer Noura Mint Seymali from Mauritania and the Grammy-nominated diva Fatoumata Diawara from Mali. Noura graces us with special backstage performance of the ancient harp, ardine. And Fatoumata sings a capella, showing us what she says is "her voice as a traditional instrument." We also hear local artists Jose Elias of Cortadito and the Grammy-nominated Danay Suarez. Along the way, we take a tour of Miami's lively local radio. Afro Roots indeed! Produced by Sean Barlow and Banning Eyre.
