The Electric Zoo Festival, a dance music festival held on New York City's Randall's Island, was cancelled Sunday after two attendees died.
Jeffrey Russ, 23, of Rochester, N.Y., and Olivia Rotondo, 20, of Providence, R.I., died from an apparent overdose of MDMA, according to The New York Daily News.
"The founders of Electric Zoo send our deepest condolences to the families of the two people who passed away this weekend," organizers said in a statement. "Because there is nothing more important to us than our patrons, we have decided in consultation with the New York City Parks Department that there will be no show today."
The festival, which was in its fifth year, was scheduled to end Sunday with headlining acts Armin Van Buuren, Sebastiona Ingrosso, Steve Aoki and Laidback Luke to perform. Tickets to the festival cost $179. Last year, it attracted 100,000 people.
Organizers said refund process information would be posted.
