Overview
Mike Servito at Dead Letter No. 9
PSYCHOSIS
continues its descent with Night Two of our four party series. Our minds are deteriorating, reality is breaking its shackles. The faces of the crowd distort, these rooms feel familiar but uncanny, like you’re trapped in a dream. Dress as the obsession gnawing on the flesh of your brain, the fear you refuse to name, the version of yourself you keep locked away, or the demon you’re ready to face. In CARGO, Acid Mama administers the first dose from 9PM–11PM, corrupting the senses with acid-soaked pressure. From 11PM–1:30AM, Sister System intensifies the spiral, driving the room further from reason and closer to total surrender. Then Mike Servito takes control from 1:30AM–3:30AM, delivering the final lethal dose as any remaining reality fades like a lost memory. The disturbance spreads to The Foyer, where beewack holds the room from 9PM–12AM, twisting familiar sounds into something unstable but undeniable. At midnight, Bea Hardy takes over until 3AM, tightening her grip as the room grows hotter, stranger, and completely unhinged
PSYCHOSIS
is a reckoning. The twisted thoughts that live in the back of our minds come crawling out, the stages of grief are embodied in flesh, and together, we face our demons before they find us first. Make it out as yourself, or as an entirely new creature – if your mind is still your own. Kitchen open late. Coat check available. 21+ All ticket sales are final
