Although Ultra Music Festival Europe was only just announced in Croatia, phase one of the lineup has already been revealed. July 12th will feature Avicii, July 13th will feature Armin Van Buuren, and both days will host the legendary Carl Cox who will be bringing his friends along. Artists for day three on Hvar Island are as of yet unannounced, but we expect the names will be just as big. Tickets are on sale now for the low price of 50 Euros (~$65) for GA or 100 euros (~$130) for VIP. Tickets include access for all three days.
