It’s safe to say that Marshmello has had the biggest special guests of Ultra Music Festival so far, bringing out the one and only Fresh Prince, Will Smith, as well as Yo Gotti, G-Eazy, Slushii, and Lil Uzi Vert. And speaking of that last one, he didn’t only bring out Lil Uzi as a guest, ‘mello premiered a new song with him.
The untitled track starts when Lil Uzi comes out at 49:55 in the mix below.
Honestly, Marshmello’s whole set was a pleasant surprise, and Ultra’s massive stage seemed like the perfect setting for him considering how heavily his set relies on bright and colorful visuals. 
The live video will be available on Marshmello’s own YouTube soon, but you can listen to the set via Mixcloud below for now!
