In 1809 the population of New Orleans doubled almost overnight because of French-speaking refugees from Cuba. You read that right, French-speaking refugees from Cuba -- part of a wave of music and culture that emigrated from east to west in the wake of the Haitian Revolution. We'll look at the distinct African roots of these three regions, and compare what their musics sound like today. In this Hip Deep edition of Afropop Worldwide, our colleague Ned Sublette, author of "Cuba and Its Music: From the First Drum to the Mambo," will talk with Dr. Gwendolyn Midlo Hall, author of "Africans in Colonial Louisiana". Produced by Ned Sublette.
