The show itself is small and controlled, a survey of the Bechers’ repeated interdiction of industrial structures over a lifetime. Seeing the actual prints, rather than muddy reproductions in art magazines, opens a crisp portal into anthropomorphic whimsy, as concept defers to form.

Grim are the associations of coal mining and steel production, of course: human sacrifice on a bower of heavy metal. Yet, the Bechers’ work is replete with humor, the laughter of space aliens visiting a future earth, extinct of humans, but full of the Bechers’ heavy toys.

Gas tanks become rolling balls and fat silos. Coal bunkers in Germany are office buildings of dust. American blast furnaces stroke themselves with monster fingers. The winding towers of Wales glide down effortlessly like roller coasters. Cooling towers in the Ruhr Valley stiffen into ladies’ corsets, while water towers from everywhere are nothing less than architectural royalty.

Repetitions of ordinary form with subtle variations in the Bechers’ opus emerge as pregnant with dignity and meaning as a Bach cantata. In these structures, born from material necessity, function becomes poetry, weightless wonders of illusion summoned from silence.
