In the early 1990's my daily commutes in the New York City subway started to become a photographic obsession. I was soon traveling underground, camera in hand, with no fixed destination but images. Aware that many photographers had been there before, I felt I understood why: the endless parade of people offered by a subway ride is irresistible for the voyeur lurking behind every camera. Over the following years that parade would lure me to spend hours hidden from the sun within the subways of New York, Caracas, London and Mexico City. When I moved to Mexico, upon descending for the first time into the underground system, a familiar feeling of joining a city's pulse and becoming one of its own hit me like a rush of blood to the head. There was that parade again, each passenger traveling with a story, an attitude, a social imprint, a mood, a book, and now... a phone. There for an instant, gone the next, always en route to an unknown destination as I watch, listen and hunt for snippets of a million endless stories. With any luck I shall press the shutter before it's too late. This particular sequence of images, shot in Mexico on 35mm B&W film, was commissioned in 2008 by Quinta Real magazine and published as an eleven-page photo essay with a short text by the photographer.
