Killer Mike is one of those artists whose efforts seem to instantly go viral—just check out his awesomely shareable music videos. Constantly sharing the stage with his friends, this weekend’s lineup itself reveals Killer Mike’s connections in the industry. He is currently touring with El-P, fellow Moogfest performer and the producer of Mike’s most recent release R.A.P. Music. At festivals, famous friendships can lead to on-stage surprises, so Killer Mike’s set at the Orange Peel is probably a safe bet.
