My sixteen-month journey with the Allentown arena began in the spring of 2013. The notion of photographing in a defined, yet ever-changing, environment for an extended period of time was compelling. With each visit, the site transformed into a dynamic new setting. The people building the arena became my collaborators. With concrete and steel, the work of human hands became an intoxicating mix to photograph and is expressed in the eight parts of CONCRETE. I am a witness to transformation.
