Diplo and Skrillex’s New Surprise Album Features Justin Bieber, 2 Chainz, Missy Elliott

Two of music’s biggest DJ producers, Skrillex and Diplo, just attempted a 24-hour DJ marathon — but that hasn’t stopped them from surprise-releasing their first collaborative album with some very special guests.

Skrillex and Diplo Present Jack Ü features Justin Bieber (his first new song in more than a year), Missy Elliott (her first new song since her Super Bowl halftime show appearance) and 2 Chainz (who raps “Yeah, I’m the sh-t / I should have Febreeze on it”). Appearances from Kiesza and AlunaGeorge also round out the 10-song set, now streaming live on SoundCloud.

Diplo’s 2015 is already off to a great start: he produced several songs for Madonna, who’s profiled in the new issue of TIME, on stands now.
