For the past few days, all of us not at Coachella have had to suffice by just living vicariously through the Tweets, Instagram photos and Vines of our friends, or the celebrities we follow, who are there. And just as we were about to congratulate ourselves for making it through weekend one without developing a serious case of FOMO, we get a video of Phoenix performing with none other than R. Kelly. No, really. R. Kelly joined the French rockers onstage during their set, where the two mashed together “1901″ with the remix for “Ignition” and then slipped into a mash-up of “Chloroform” (off Phoenix’s forthcoming album Bankrupt!) with “I’m a Flirt.” Watch the fan footage above, or as Pitchfork points out, a fairly good audio rip of the performance here.
