Eccentric and reclusive performer Sir Ivan welcomes a gaggle of outlandishly dressed city folk to his Neverland-inspired Long Island compound for his new single and music video, “La La Land,” release party. But don’t show up in your typical day look: anyone not dressed “extreme”—whatever that means—will be denied entry. 8pm–midnight; free. Email sirivanrsvp@gmail.com for more info.
