Host Jacob Edgar's journeys through Colombia reveal the country's amazing geographical, cultural and musical diversity. This time, his travels take him from the ranches and farmlands of Valledupar through the Sierra Nevada de Santa Marta mountain range and on to the Caribbean coast. The small city of Valledupar is the cradle of vallenato, a rustic, folksy and distinctly Colombian music style. There, Edgar meets Fonseca, one of Colombia's biggest stars, who has incorporated the vallenato style into the tropipop sound he made famous. He meets with the Rey de Reyes (King of Kings) of the accordion, attends a wild street party, visits a restaurant that serves unusual wildlife and joins the adorable Los Ninos de Vallenato for a performance in the city's main square. Next, he travels to a small coastal village to meet with a former paramilitary soldier-turned-vallenato-singer, who serenades from a fishing boat in the picturesque harbor. Finally, Edgar ends up in the port city of Barranquilla, where steamy, tropical Afro-Colombian beats dominate the music scene. At a rehearsal for Barranquilla's famous carnival, singer Erika Munoz gives an impromptu performance of her African-influenced sound. Colombian legend Joe Arroyo performs with his full 14-piece band in a commandeered library.
