Eminem & Slaughterhouse Live in NYC (Video)

No, they don't actually perform together but they do both rock at the same Red Bull sponsored event. First Em rocks his "Despicable" freestyle and then goes into "On Fire" while Slaughterhouse rocks their most popular single "One". By the way, this is just after Eminem rocked "Renegade" with Jay-Z on the roof of the David Letterman show in NYC.
