DJ Marshmello teamed up with Guatemalan-American DJ Carnage to release a new song, “Back In Time,” which follows up the collaboration song “Leave Before You Love Me” with pop band Jonas Brothers, which was released last week. "Back In Time" is an interesting departure for both artists, who have been known in recent years to keep fans on their toes in terms of genre. Influenced by late-80s Eurodance music, the song attempts to harken back to the rave scene of the era by interpolating old-school synths with a pulsing bassline.

No word yet whether or not "Back In Time" will appear on Marshmello's upcoming album.
