Electric Zoo will offer full refunds to festival-goers after yesterday's events were canceled following the deaths of two attendees, the New York City festival announced on its website.
Those who bought three-day passes will receive a 33 percent refund, while customers who purchased a combo pass for Friday and Sunday will receive a 50 percent refund.
Along with the two deaths, at least four other Electric Zoo attendees were placed in intensive care after falling ill. The authorities suspect that the concentrated form of MDMA known as "molly" is to blame in all cases. Performers slated for Sunday had included Sebastian Ingrosso, Steve Aoki, Diplo, and Zedd.
"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," the festival said in a statement over the weekend.
