Young people are crowding underground phone-free parties. I went to one.

NEW YORK — The alcohol is flowing, music is bumping and partygoers are writhing against each other on the dance floor.

I reach into the back pocket of my jeans to capture the moment with my phone, and realize the spot is empty.

I’m at a phone-free party in Brooklyn, and it’s nothing like I expected.

A flyer for the party promised “a celebration of social life as it’s meant to be: free from the grip of greedy tech platforms” along with immersive art, rituals and DJ sets.

By the time I reach the unmarked door in Brooklyn’s East Williamsburg neighborhood, I can already hear the house music pulsing through the walls. Inside, I hand over my phone to an organizer, who places it into a cubby alongside dozens of others. In its place, I carry a clunky old-school microphone, a notepad and a pencil.
