I started to think a lot about music when I knew I’d be talking to Chuck D, the rapper and frontman of the hip hop group Public Enemy. I related to the rock and roll of the Beatles and the Rolling Stones. Rap was from a different generation. Some critics point to Public Enemy as the revolutionary voice in hip hop which helped to plant the genre in the heart of American culture. Chuck D and Flavor Flav formed Public Enemy in 1985 and the group became known for its political messages on albums like Fear of a Black Planet. But in the decades since he first became a legendary hip hop artist, Chuck D developed his talent as an artist illustrating three graphic books. His latest, Rap Pilates, is about the exercise he credits with helping him to perform high-energy concerts. We talk about drawing, creativity and changing the world.
