Contributed by Patrick Neal / Stephen Maine’s abstract paintings, on view at Private Public Gallery in Hudson, NY, hit you head-on with their optically charged surfaces and imposing presence. The gallery, which has a penchant for showing large-scale work, is exhibiting in its main space several of Maine’s signature “residue paintings” – spongy, all-over compositions with gorgeous, saturated colors in acrylic on canvas – that are over eight feet by six feet.
