Dead Letter No. 9 serves as an immersive nightlife space in the Williamsburg neighborhood of Brooklyn, New York. Housed in a former postal facility, the venue blends theatrical design with a social cocktail bar experience across several transportive, themed rooms. The back area, known as Cargo, functions as a dedicated dance floor featuring house and electronic programming. This event brings together Zach Witness, ellen.j, LeBRON, and Joopiter for a night of club-focused music within the venue's distinct, storybook atmosphere.
