It looks like the cautionary measures and logistical overhauls facing electronic events in 2014 aren't quite through yet: Ultra Music Festival just announced that they're changing their all-ages policy and requiring that all ticket holders be at least 18 years of age.
From the festival organizers:
“While we sincerely value the incredible ongoing support from our younger fans, we ultimately believe that Ultra Music Festival is a premium event geared towards adults. This decision has been made to reinforce and promote the safety of all Ultra Music Festival fans and to ensure the overall enjoyment of all future attendees. We are extremely grateful for all the support we have received from our younger fan base to date, and we encourage them to attend the festival once they reach the appropriate age. Until then, our free YouTube stream, ‘ULTRA LIVE’ is available worldwide for everyone, all ages to enjoy and to share in the Ultra experience.”
Despite the last-minute headliner change-ups due to serious illness and security catastrophes that had the Mayor of Miami considering banning the festival on the whole, Ultra's prevailing after a rough year and making the safety of its attendees its utmost priority in the coming months.
Ultra isn't the only EDM festival to head back to the drawing board on the safety front front: Electric Zoo introduced stricter security measures this year and required all festival attendees to watch an anti-drug PSA before entering the EZoo grounds.
