As Kendrick Lamar trekked through North Carolina this week, he was joined by a very special guest. J. Cole, who's having an incredible week with all this new music, surprised the crowd with a live appearance—and they loved it. The rapper joined his West Coast friend to perform "Power Trip" and then Lamar's hit "Drank."

Take a look/listen below (mind the poor audio quality, as it's via crowd footage).
