In bright white ensembles, G.O.O.D. Music opened Sunday's BET Awards. Big Sean, Pusha T and an enormously-applauded 2 Chainz performed their "Mercy" verses. After, Kanye West appeared to perform "Cold" and to preach a verse from "New God Flow," his upcoming single with Pusha T, accompanied only by the sound of his own stomping foot. Watch that above. Below, watch Nicki Minaj perform "Champions" and "Beez in the Trap" (also featuring 2 Chainz, this time wearing black) with an orchestra, and Usher do "Climax."
