At the idyllic Sankeien, a traditional Japanese garden and the Triennale’s fourth main venue, a fascinating, eerie pallor suffuses the art on view. Misty waves of man-made fog from Nakaya Fujiko’s Fogfalls #47670 ‘Tales of Ugetsu’ seep through the trees, setting a tone borne out in Jorge Macchi and Edgardo Rudnitzky’s minimalist installation Twilight. Set in an old dark temple, this latter work features a single fading light bulb attached to a wire moving ever so slowly across the room. One Tokyo gallerist lamented, “It looks stolen from a Hijikata performance I saw in the ’70s.”
