Gordon Matta-Clark / 112 Green Street

In 1975 the young American artist Gordon Matta-Clark took a chainsaw to a perfectly ordinary single family house in Englewood, New Jersey and split it in two. While the stunt smacked of bad-boy behavior and art world sensationalism, it was hardly an act of anarchy or desperation. Rather, it was the intervention of an artist with the keenest sensitivities renouncing commercialism in search of a more elemental understanding of space and materials.
