ULTRA MUSIC FESTIVAL 2015 has announced a new stage concept, "Resistance" which Ultra describes is "the urge to go against the grain, to step out of the box, to move away from the norm and challenge yourself to experience something new– to break down boundaries and barriers and abandon your comfort zone– to be able to open your eyes and ears to an undiscovered realm of electronic music." The lineup includes the likes of Sasha, Jamie Jomes, Pete Tong, UMEK and Totally Enormous Extinct Dinosaurs. Check out the full lineup on the poster above. They join Afrojack, Alesson, Avicii and others announced in the Phase 1 lineup. Check the full lineup and ticket details on The Ultra Music Festival official website.
