The annual electronic music festival Electric Zoo has cancelled its final day due to “serious health risks.” As of press time, two fans have died of drug-related causes at the festival and several others have been placed in intensive care. New York’s Randall’s Island has hosted Electric Zoo since its inception in 2009. This year’s lineup featured A-Trak, Big Gigantic, Diplo, Bassnectar, John Digwood, Four Tet and many others.

A message from the city’s official homepage NYC.gov reads:

Due to serious health risks, the Electric Zoo music festival on Randall’s Island on Sunday, September 1st has been cancelled. The City recommended cancellation and the event promoters have agreed.

During the first two days of the Electric Zoo music festival, two concert-goers have died and at least four others became critically ill and have been placed in intensive care at area hospitals. Definitive causes of death have not yet been determined, however, both appear to have involved the drug MDMA (ecstasy, or molly). The Electric Zoo organizers have worked with City officials to reduce health risks at this event, but in view of these occurrences, the safest course is to cancel the remaining day of the event.

Electric Zoo was slated to run through this evening. A note from the festival’s promoters says, “The founders of Electric Zoo send our deepest condolences to the families of the two people who passed away this weekend. 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.” Refund information will be made available soon.
