This week, Kendrick Lamar’s Kunta’s Groove Sessions tour will officially begin. Before heading out, Lamar played a handful of shows including a series of radio station festivals.

Last night he was in Columbus, OH for 106.7 The Beat’s Birthday Bash, where he made sure the show was particularly special for one audience member. Right as he was about to dive into “m.A.A.d City,” Lamar invited a fan up on stage to perform the song with him. And honestly, dude kills it.
