Many local creative groups and individual artists have reaped the benefits of cooperative event planning, and the galleries at Chestnut Square are in the midst of creating a successful mini-scene of their own. While the space has housed artists and galleries over the years, it’s been some time since I’ve seen coordinated shows or even a plethora of regular happenings at Chestnut Square. Seed Space has recently made some good noise with their Community Supported Art project, and tonight they’re opening Ryder Richards’ Breech: a compelling installation that anthropomorphizes the architecture of the gallery while taking aesthetic cues from the patterning on the decorative breech of a Winchester rifle. Adding to the location’s roster of art galleries, Sara Estes and Dane Carder started banging out consistently strong exhibits of contemporary fine art at Threesquared last year. The duo’s doings have been smartly promoted through web-savvy exhibition preview videos, and tonight Threesquared opens a show by painter Patrick Brien. Brien’s geometric abstracts borrow from modern architectural forms, but it’s their humanity that strikes me. His “Cantilever” is full of panic and shame, and infused with a Guston-esque blush of oranges and whites. “Frost Haus” includes a blue element that looks like an architectural drawing of a boat or a plane. At the bottom of the painting, in black negative space, a blood red smear opened a trapdoor beneath my feet, dropping me from the airy heights of conceptual distraction back down to this brutal life we each live alone and in the dark. Oh yeah, Happy St. Patrick’s Day!
