The piece, which follows the trajectories of five characters as they make their way through nocturnal New York, explores Aitken's key recurring themes: broken and recombined narratives, the rhythm and flow of information and images, and the relationship of individuals to their environment. The viewer, as a pedestrian, a participant and a vital component of New York's energetic system, becomes part of the work, and of the interactive personal landscape that Aitken creates in and among the hard-edged concrete and glass language of Manhattan's architecture. In addition to documentation of , this publication contains an overview of the artist's work to date, with special emphasis on works since 2001. It also contains conversations between Aitken and a variety of artists, architects, writers and performers about different elements of city life, from the lit signage of Times Square to a taxi driver's eye view of the streets.
