Dylan Stone is one of the better under-known conceptualists around. Schooled in New York, this current London resident has previously sewn on newspapers and compiled a photographic archive of every building in Lower Manhattan. Lately, he’s made nicely dicey miniature sculptures of his sexual encounters (on view in the gallery office). Barbara & David Stone’s Bookshelf is a huge, indexical, magical, and magnificent example of abstract portraiture and self-portraiture. We see a wall-filling, multipaneled watercolor, based on a photograph of his parents’ library. The books suggest intellectuals or academics. It turns out, Stone’s parents produced some of the art world’s greatest experimental films. The overall effect is a mesmerizing tour de force of verisimilitude, love, and intimidation.
