Video : https://vimeo.com/123690848 Skrillex & Diplo & DJ Snake & Kiesza & Diddy & Justin Bieber Ultra Music Festival knew what they were doing when they tasked Skrillex with the job of closing out their iconic mainstage tonight in Miami.The last set of the night is where UMF’s history-making moments go down – it’s where Swedish House Mafia played their last ever show in 2013 and where Deadmau5 infamously trolled the crowd last year – and in 2015, there’s no one better to deliver an unforgettable hour than OWSLA’s commander-in-chief.Skrillex definitely delivered. Just as the rumours had it, after 50 minutes of bass weapons Sonny Moore brought out one Justin Bieber for a very special guest appearance. First lip-syncing the words to Where Are U Now, his collaboration with Jack U, Biebs then danced at the front of the stage before hopping up on the decks to watch fireworks close out the set.But Bieber wasn’t the only special guest Skrillex had up his sleeve. His star-studded hour saw cameo appearances from DJ Snake (who came out to drop Turn Down For What, naturally), Jack U collaborator Diplo and their Take U There vocalist Kiesza, plus a curveball appearance from Diddy and a cast of other singers.Skrillex’s closing set means that Ultra is over for another year.
