Our celebration of the 50th anniversary of hip-hop continues with Ahmir "Questlove" Thompson, drummer and co-founder of The Roots. He was born in 1971 and says he and hip-hop grew up together. Also, Public Enemy's Chuck D talks about the song "Fight the Power" and the powers they were fighting. And we'll listen back to a conversation with Sean "P. Diddy" Combs, A.K.A. Puff Daddy. He made his name—or names—in the hip-hop world as a record producer and rapper.
