Yesterday, Kanye West served up the lead single in support of the forthcoming G.O.O.D. Music album Cruel Winter, "Champions." He also stopped by L.A. radio legend Big Boy's current radio show to discuss the single, the forthcoming album from his crew and more. Last night, Kanye West joined Big Sean onstage for the live debut of "Champions." Performing a headlining set for the annual Powerhouse event in Los Angeles, Big Sean decided to bring out his label boss to perform a round of select hits. Kanye also performed a couple songs off his The Life of Pablo, including "Famous" and "Father Stretch My Hands Pt. 1." You can watch some footage from the outing below.
