The city says it recommended Electric Zoo festival not continue Sunday after two people died and four others had to be hospitalized during the first two days of performances on Friday and Saturday. The festival took place on Randall's Island in the East River.
The city says the deaths appear to have been linked to drugs, specifically MDMA, or ecstasy. Definitive causes of death have not yet been determined.
The event's founders expressed condolences on its website to the families of those who died.
The festival has been held over Labor Day weekend since 2009.
