Say what you will about Black Thought. He’s not always the most exciting rapper, he can be a little cold, he’s not super-lyrical. But damn can he rip a mic live. Watch as he destroys the David Letterman show, with a drum-tight band behind him. Every single word is clear — no hypeman finishing his lines or any other BS. Every line ends stronger than it began. Does this dude have gills behind his ears like Kevin Costner in Waterworld? When does he breathe?
