It's the lights, the crowd, the sunshine, the production, and most importantly the music of course, that make Ultra Music Festival one of the most legendary music festivals in the world, always keeping us coming back for more each year. Going to Ultra is an unforgettable experience, one so impressive that those who attend will attest to the memory lingering with them for months afterward. This year, those lingering feelings have the numbers behind them to support them: the number one trend online for three days straight, almost 10 million people tuning in worldwide to watch the live stream, and artists like Armin van Buuren, Steve Angello, W&W and Hardwell gracing a main stage setup so out of this world that it needed its own name: The Vortex. As we now try to continue to snap back to reality, we've been revisiting our WMC Instagram Diary and reminiscing about the memorable week. Though it's probably not the most productive strategy, we just can't shake the memories and have compiled our favorite Instagram photos from the festival's 16th annual run below. Don't worry: Ultra has announced the dates of the festival for next year as March 27, 28 and 29, 2015. Keep up with the festival announcements HERE, and of course follow Ultra's own Instagram HERE.
