Digital Grange in Petaluma is a fine-arts service that specializes in (surprise!) digital imaging and graphic design. Their clients include the de Young in San Francisco and the Art Institute of Chicago, and now the collective opens its own gallery in the ivy-covered Burdell Building next door to their offices. IceHouse Gallery will feature Digital Grange’s impressive roster of artists, such as Chester Arnold (whose art is pictured below) and modern surrealist Don MacDonald. The gallery’s inaugural exhibit, “Landscapes,” opens with a reception April 18 at IceHouse Gallery, 405 East D St., Petaluma. 6pm. Free. 707.778.2238.
