Raider Klan (12:45 PM Sunday, Outdoor Theatre): SpaceGhostPurrp is one of the most interesting kids churning out dank hip-hop beats and has the ominous rapping chops to match. He and his youth crew Raider Klan will cast a looming, murky atmosphere across one of Coachella’s biggest stages that will turn one of the opening performances of the day into a late-night basement romp. Pro-tip: If you’re unfamiliar with the group’s breadth, RK’s first lady and total gem Amber London is set to wow with her mellow attitude and waxy jam “Low MF Key.”
