Contributed by Adam Simon / One of Russell Maltz’s singular achievements is to demonstrate how easily utilitarian objects and materials can be transported, Cinderella-like, into the alchemical realm of fine art. This is partly a property of the materials themselves: the symmetry, weightiness, and economy of products meant for construction. “Russell Maltz: Painted/Stacked/Site” on view at Minus Space in Dumbo, through July 30, with an additional nearby storefront installation and a slide show depicting found sites of construction material.
