Matt Crawford speaks with author Dr. Todd Boyd about his book, Rappers Deluxe: How Hip Hop Made the World. This is a visual and cerebral journey through 50 years of Hip Hop evolution. As only Dr. Boyd can do, he takes us by the hand and leads us through the pivotal moments in Hip Hop culture, Rap and history to provide the context that is so often missing and helps us to understand the true meaning of this movement.
