After watching Macklemore lay waste to the competition at the Grammys, Kendrick Lamar and the TDE crew took matters into their own hands with a “fan appreciation show” at the House of Blues.

Kendrick took the opportunity to bring a fan up on stage and trade bars over “Rigamortis.” The guy actually holds his own—Kendrick does well not to embarrass him too much, and the crowd doesn’t boo him off the stage. When you’re freestyling with the king of New York, anything more than that is a respectable showing.
