At Coachella a few months ago, Jamie xx drew a pretty big crowd to one of the side tents, but his album wasn’t out yet, and the mass of kids mostly just danced politely. Things done changed. Those pretty architectural house tracks have become anthems, especially the Young Thug/Popcaan track that’s one of the year’s best singles. The crowd went absolutely bugshit when they heard the song’s Persuasions sample, and Jamie xx kept delaying the gratification, playing all of the Persuasions song before letting his own track drop. And when it kicked in, the earth moved. It’s weird to see Jamie xx on a festival stage, since he doesn’t really do anything other than play the records. But if he comes off more as DJ than performer, he’s learned to do the thing every great DJ has to know how to do. He can now move the crowd.
