Ry Fyan’s dystopian architectural fantasies have all the complexity and meticulous visual invention of, as the artist puts it, “drawings on a notebook from childhood.” Improvisational in method, yet drawn from a number of remembered sources, Fyan’s drawings represent a bleak vision of American power. In The Metropolitan Meth Silo, a many-turreted castle, US flags flapping from its pinnacles, crouches on the horizon against a sickly sky. Small human figures scuttle in its shadow, but there’s no sense of the building being enterable; its grand arches seem bricked-up, a vision of authority at odds with the world around it. The drawing’s title makes some unnervingly jarring references to the Metropolitan Museum of Art in New York and the epidemic of methamphetamine abuse in America, the juxtaposition calling upon different structures of power in its feverish collision of signs.
