"Ghost Hardware," Sean Dack's latest exhibition at New York's Daniel Reich Gallery, builds a visual language, in photography and sculpture, from the limits of technological legibility. Over a series of unique c-prints, thoughtfully hung throughout the gallery, Dack coats a panoply of sourced images with thick layers of digital interference: glitches that "tangle and halt the flow of information," but in so doing also provide the precondition for the exhibited art-objects. Formally, these images are beautiful, their striated lines of pixels at times staining underlying images in cyan and magenta; at others, reducing them to wholly abstract geometries. These techniques prove most effective when echoing the sourced images, as when Dack's pixels form postmodern building block analogues to the structural units of the unfinished, contemporary skyscrapers in Building (Hotel, Pyongyang) (2008) and CCTV #2 (2007). Yet on a broader level, Dack's choice of images risks belaboring his conceptual inquiry. Shots of isolated women, an airborne helicopter, unmarked CIA airplane and a missile test quickly move the exhibition into well-trodden, conspiracy theory terrain. One wonders whether Dack's Pop sensibility - most explicitly manifest in his rubber encasings of obsolete tape decks and CD changers, also on display - extends into the realm of his photographs' subject-matter and thus justifies the indulgence. Whether or not this is the case, the artist's formal investigation of the psychic life of digital technology would be far more interesting without its narrative props. - Tyler Coburn
