If you’ve ever wanted a glimpse of what star-studded club culture is like, you probably won’t get it at #ZoomFest. In fact, you may not ever get it again, according to Ronnie Madra, co-founder of the illustrious 1Oak nightclub in New York City, where celebs such as Jay-Z and Beyoncé, Rihanna, the Kardashians, Leonardo DiCaprio, Katy Perry and many, many more are known to hang. “As an operator, as a nightclub person or hospitality person, I don’t see myself going back to business as usual, unless there are major changes being made,” Madra tells The Post after recently founding the fledgling digital music and entertainment festival ZoomFest.
