The city suspended in the enduring aesthetic of noir. Daniel Sackheim's The City Unseen brings to life desolate streets and shadowed alleyways, a dance of light and darkness that reveals the dual nature of a city; in images deeply sculpted from shadow he presents beauty intertwined with uncertainty, a recognisably contemporary city that is timeless in its sense of apprehension and disorientation. An Emmy Award-winning film and television director, Sackheim turns his cinematically trained eye to the labyrinth of the urban night, drawing on the formal language of film noir and on the voyeur's noir of Sudden Fear and Touch of Evil, whose compositions echo the oblique, elevated viewpoints of an observer at the margins that he describes in his introduction. The pictures were made in Los Angeles, a city where the brightest sun casts the deepest shadows, and explore the tensions between light and dark, glamour and decay: a liminal realm that is as much a real place as a state of mind.
