Kelly Akashi’s poetic assemblages of sculpture in glass, stone, bronze and rammed earth at Tanya Bonakdar Gallery heighten awareness of her materials and processes while juxtaposing human concepts of time with comparatively vast measures of time on earth and in the universe. Here, the glass sphere titled ‘Cosmic Axis,’ brings to mind the axis around which the earth rotates while also alluding to the connection between heavenly and terrestrial realms. Surrounded by photos of distant nebula taken by telescopes, the sculpture feels especially present in the space of the gallery, its delicacy contrasted by a large concrete pedestal and enhanced by cherry blossoms on top that extend into the space of the sphere. (On view in Chelsea through June 10th).
