What's The Deal With Saul Williams?

So, he's got a VERY compelling stage presence and seems like a nice, funny guy. Tight band also. However, they only played new songs, most of which didn't seem great.

Almost the best part was in the encore, when he did Coded Language acappella and totally killed it. Then said "I don't know what any of that means".
