DJs Lauren Flax, Rose Kourts, Serrian, CatLadyHi and Lady Harley play the first night of Psychosis, a two-night Halloween-adjacent dance party at 63 Grand St. Themed around dark, depraved crevices of the mind, it kicks off a four-night Halloween series.
Think less “nightlife hang” and more “evening you remember.” In a former Williamsburg post office, this immersive experience invites you to wander free through sets that feel like cabins in Joshua Tree, porches in the Smokies, treehouses. Each space built to pull conversation out of you. You move at your own pace (90 minutes total), meet strangers, share stories, explore ideas prompted by guides, then settle in afterward in the bar-restaurant or dance in their nightclub “Cargo.” It’s for people who want connection, curiosity, and a night that’s more than drinks + music.
