Mos Def & Talib Kweli On The Colbert Report

"Nope. I am not using Mos Def as a professional name anymore," he said. Stephen Colbert, the show's host made light of this, asking, "Why would you not be Mos Def anymore? He's a famous guy who sells records. Why would you do that?"

"Underground Rap is a label we never really understood," Yasiin noted. "What does it mean? Is it that we don't rhyme above sea level? I don't know. But, there's a lot of diversity in Hip Hop, there's a lot of different styles across all different genres of art. People like to label things, I guess...We just do what we do, underground or above ground."
