New York City's Meatpacking District is known today for glitz and glamour, but it used to be famed for blood, muscle, and sweat. When photographer Pamela Greene first visited this area, she found a 24-hour neighborhood that changed daily, from a gritty industrial site to a sophisticated play ground, and back again, by dawn. She photographed it all, capturing the electric energy of the streets, and a nightly frenzy underground of strippers, singers, gays, straights, and on occasion, prostitutes. In 120 raw images, Greene gives us a portrait of change, an ode to urban transformation, and an elegy for workers who have disappeared into New York City history.
