This has been a fascinating series. We watched the second one tonight which was in Cuba. Both shows started out with music of the slave/black cultures. Well worth watching, imo. I found this blurb about it HERE.

"Cuba: The Next Revolution"

In Cuba, Gates finds out how the culture, religion, politics and music of this island are inextricably linked to the huge amount of slave labor imported to produce its enormously profitable 19th century sugar industry, and how race and racism have fared since Fidel Castro's Communist revolution in 1959.
