Get ready, EDM fans: Ultra has just announced the first phase of its 2015 lineup, and it doesn't look like you'll be spending a whole lot of time standing still in Miami. You're going to be dancing your face off. It's basically guaranteed. Don't believe us? Just take a look at the headliners alone and you'll be booking your flights now if you haven't already. 

It appears that Avicii is making up for lost time (he had to cancel last year's headlining Ultra set due to a medical emergency), and he shares this year's top billing with Skrillex, David Guetta, Steve Aoki, Kiesza, Bassnectar, Krewella and more. 

In total, 36 headliners (!!!) split between DJs and live performers and an additional 73 acts make up the first round of EDM fiends to join Ultra's Class of 2015. If this is what they're leading with, we can't wait to see what Phase 2 will bring.

Ultra kicks off March 27 in Miami. Check out the Ultra 2015 lineup in full here, and be sure to loop back for more information on the festival by heading on over here.
