When we tell people were photographing for basically about four years, that doesn’t sound like a lot of time, until you consider what a condensed period that was. You had the real-estate boom in 2004, '05, '06—where people were moving to Harlem, housing prices for Brownstones were skyrocketing. There was this wave. We made our first pictures in 2007/2008 and then in late 2008, with the crash, suddenly this optimism burst like a balloon. You literally had holes in the ground because people had not only warehoused buildings, but they had also torn them down in anticipation of this development that was on the board and then just stopped. It was like a mouth that was missing teeth. You just had these blocks with buildings gone, businesses gone, that had been there for 20 to 30 years, a lot happened in that period. Toward the end of the project we started to get a sense, okay now these things, these projects, are back online. It was a very dense period of rapid transformation.
