About the party

PSYCHOSIS, night two of Dead Letter No. 9's four-party Halloween-season series, takes over the bar at 63 Grand Street in Williamsburg, Brooklyn, on Saturday, October 24, 2026, from 9 PM to 4 AM per DICE. Mike Servito headlines the CARGO room, with Sister System, Acid Mama, beewack, Bea Hardy and Love Language across three spaces.

What to expect

The theme is psychological horror: the organizers ask guests to dress as the obsession gnawing at your brain, your locked-away self, or the demon you are ready to face. Costumes are invited, not stated as required. My take: for people who like a themed dress-up night with a real DJ bill. Dead Letter No. 9 says October 31 is its last day open, so this is one of its final weekends.
