Donald Glover, a.k.a Childish Gambino, gave one hell of a Coachella performance last night, where he held a glaring mirror up to his massive crowd and made them all feel real bad about their festival behavior. (He also debuted a tropical drama with Rihanna! What a day.) Pick a pew and listen to his sermon, fools: Next time you see him perform live, don’t even think about doing anything for the ‘Gram. Because as tempting as it is in the name of good #content, he’ll happily call you out, and it’ll get awkward. “Put your phones down. This is not a concert, this is church. If you came here to hear your favorite song, you should go home and do that,” he told the crowd mid-set. “If you want to come here to just take Instagram pictures and shit, you should go in the back and move right now. I want y’all to feel this shit. This is my church. I feel at home here.” We’re assuming this ban also pertains to Snapchat, Twitter, and Slack, sorry!
