The Chainsmokers have been teasing their set at the Los Angeles Convention Center, presented by Insomniac and Exchange LA, for a long while now, poised to be one of their biggest solo headlining shows of their career. Following up the debut electronic show at the venue by Kaskade is no small feat, but if anyone could do it, it was The Chainsmokers.

With a show of such magnitude, you would expect them to bring out some surprises. At Coachella, they managed to bring out G-Eazy, Third Eye Blind and even Tiesto.

For their LACC Dreaming show, they brought out the motherf*cking Backstreet Boys.

Another guest at the show was Big Sean, but come on… once you bring the Backstreet Boys on stage, you’ve already won.
