In limestone, a key component of concrete, Hatakeyama sees Earth’s geologic past and its urban future. “The quarries and the cities,” he has written, “are like negative and positive images of a single photograph.” Hatakeyama began his extended Blast series in 1995. The photographs, taken with a remote-controlled camera, were coordinated with an explosives expert who directed where the blasted rock flew while the artist’s camera stopped the limestone in mid-air.
