Hip-Hop Week: Darryl McDaniels (DMC) / LL Cool J

We continue our celebration of the 50th anniversary of hip-hop with Darryl McDaniels, co-founder of one of rap's oldest groups, Run-DMC. We'll also hear from LL Cool J, and from record producer Nile Rodgers, the guitarist and co-founder of the disco group Chic. He'll talk about coming up with the bass line for the song "Good Times" which was used in Sugar Hill Gang's "Rapper's Delight."
