Regardless of who may or may not be under the mask, and we certainly have our theories, Marshmello is still known to put on a great show. At Lollapalooza this past weekend he was in full effect. This clip shows a part of Marsmello’s set where he mixes in Kendrick Lamar’s m.A.A.d City. The crowd is rapping the song perfectly while jumping up and down in sync. The crowd certainly looks to be having the time of their lives, and our only question is : was Malia Obama in that crowd or did she skip out on what appears to be a raging crowd?
