Made Event's Electric Zoo, New York's biggest electronic-dance-music festival, returns to Randall's Island Park on Labor Day Weekend, ringing in its sixth year with the usual sprawling lineup of DJ megastars. (Check out our guide to Electric Zoo for the day-by-day rundown and head over to electriczoofestival.com to nab your tickets.) The festival calls it quits at 11pm every day, but that doesn't mean you have to: Take a quick disco nap, then dance into the wee hours at these official after-parties.
