It is a measure of how healthy OC's art scene is these days that we actually had to think long and hard about which gallery most deserved this year's blue ribbon. Space on Spurgeon has been showing some great stuff, as has the J. Flynn (well, until it closed), @Space and a dozen others we could name. But when we think of the gallery we're most consistently wowed by, we have to go with the Grand Central Art Center's Rental and Sales Gallery. From their February "Subsumere: Assemblage" show (featuring the killer trio of Barry Krammes, Rebecca Edwards and previous Weekly Best Visual Artist winner Janice Lowry) to their "Happy Show" (which made us very happy indeed), this Cal State Fullerton-supported gallery has been a reliable mind-blower.
