As they relate to the art world, the complementary notions of center and periphery are still a touchy subject. Are you in the center, moving towards it or so far out on the periphery that you established a center of your own? David Zwirner gallery plays with these notions in “People who work here.” This staff show combines the work of sixteen of the employees of David Zwirner, whose day jobs range from art handler to registrar. The curators James Morrill and Chris Rawson, controller and archivist at David Zwirner, also run Rawson Projects, an emerging Brooklyn-based gallery. Upending the center and periphery of the inner workings of a gallery, the show touches on the tension between art and work: making art is work, but artists often need day jobs to survive. The curators worked without a curatorial agenda, presenting works across a broad range of media, including painting, drawing, sculpture and installation. The result is a fresh and unpretentious exhibition, a true summer show, deserving the third place for honoring the people who make all the other “blue chip” shows happen.
