The Red Bull Culture Clash is an event at which four different crews from four different genres on four different stages compete against each other for the crowd's attention. This week, London's Wembley Arena hosted a Culture Clash featuring Major Lazer, Boy Better Know (Wiley, Skepta, JME, Jammer, and others), Channel One (Mikey Dread and Ras Kayleb) , and Annie Mac Presents Magnetic Man (featuring Redlight, Rudimental, and Disclosure).
Each crew brought out a bunch of guests, including Katy B, Lethal Bizzle, Luciano, Ms Dynamite, Example, and more. But during Major Lazer's set, after an appareance by Rita Ora, the crowd was treated to a very special guest: Usher. He performed a straightforward version of the Diplo-produced "Climax", then offered up a live remix of the song. (Despite this, Boy Better Know ended up winning the Clash.)
