A young woman, letting the rhythm of the street—rather than street signs—guide her steps, disappears among the concrete blocks. This eerie stroll beneath New York’s asphalt reveals the foreign pulse beating through the city’s invisible veins. The documentary by Harvey Keith opens the door to a dark world far removed from tourist postcards. Spanning from unsettling impromptu performances on the Central Park lawns to dimly lit performance art, this flow lays bare the city’s unsettling, underground face. These performance art scenes, steeped in the dust of the streets, completely shatter the familiar silhouette of the metropolis.
