After years of setbacks, Florida’s Ultra Music Festival is leaving Miami in search of a new permanent home. In an open letter posted today (May 8) on the festival’s Twitter account, organizers stated that they had “voluntarily terminated our City of Miami license and thank them for being a part of our story for the past two decades.” The letter went on to say that the festival is “now finalizing a new South Florida location that will serve as an incredible and permanent home for Ultra Music Festival.” Find the full letter below.

The news follows years of issues related to the festival. Back in 2014, a security guard was trampled by concertgoers, winding up in critical condition. The incident eventually led Miami city officials (including the Mayor) to call for an end to the festival. That same weekend, a man died at Ultra. More recently, a new study found that high sound levels from this year’s festival caused “a significant stress response” in fish swimming in waters near the Ultra’s site. The sound created stress levels similar to the ones that fish would experience if they were being chased by a predator.

This year’s Ultra Music Festival was held at Virginia Key—an island connected to mainland Miami by a single highway. In addition to distressed fish, Ultra’s free shuttle service was overwhelmed and eventually suspended at this year’s festival, forcing many concertgoers to walk two-and-a-half miles from Virginia Key back to the mainland, according to a report by Billboard.

Ultra addressed this year’s festival in their letter, stating: “After listening to feedback from many of you (including over 20,000 fans who took our post-event survey) it is clear that the festival experience on Virginia Key was simply not good enough.”
