Sterling Ruby (b. 1972) makes a strong impression. His esthetic is masculine and a little bruised, antisocial and smart, grounded in its materials, and seems completely unpredictable. His varied output includes 18-foot-tall phallic “stalagmites” dripping with seemingly viscous urethane; rough-hewn ceramics with primordial glazes; paintings done with Robitussin-red nail polish or graffiti-like spray-paint; sculptures of smudged and scratched white minimalist forms; bus-sized cages on wheels; and videos of frustrated male pornstars masturbating to no end. For his latest exhibition, Ruby has turned to a classic Goth theme -- vampires.
