I didn't actually watch that, but thats Yorel. He's an up-and-coming underground rapper, or soemthing like that.
Nemo, you might like him, he's a bit like Talib Kweli; socially conscious and spiritual, and very intelligent. He might not be as good an MC as Talib (few are), but his lyrics are pretty great. He's an interesting guy... his songs have a lot about how 9/11 effects New Yorkers psychologically. His uncle was the co-pilot of United 93, so it's personal to him.
