Marshmello might have stolen the show with Will Smith at Ultra Miami's main stage, but the Chainsmokers have enough mega-hits to blow minds on their own. Of course, "Closer" is the big one, and because it's Ultra's main stage, you've got to bring guests.

Halsey was there in the flesh to perform "Closer" in all its glory.  Drew Taggart said he'd waited the song's two years of life to perform it in such a way on that very stage. It was a heartfelt moment, a victory lap for sure. 

 The Chainsmokers were crowned the no. 1 DJs of the year on the Billboard Dance 100 earlier this week.

Ultra has way more surprises to come in celebration of its 20th anniversary edition. Stay tuned for more special guest performances with other headliners, and watch the live clip of "Closer" and the full performance stream below.
