Last night Kendrick Lamar performed as the first-ever musical guest on Late Night with Stephen Colbert. The Compton rap savior did a medley of songs from his sophomore album To Pimp a Butterfly: "Wesley's Theory," "Momma," "King Kunta" and "u."

His whole body convulsed as if he couldn't control himself, yet his verses about suffering in black America sounded as sharp as ever. Watch below.
