A truly synergetic art endeavor, the new exhibit ‘Three Artists Collaborate’ features paintings completed in cooperation among veteran artists and longtime friends Sam Roloff, Shawn Webber and Joseph Paul Lichnovsky. Collectively known as the Milk Bar Crew, the Portland-based Roloff and Bay Area–based Webber and Lichnovsky have spent a year exchanging paintings and adding layers of realism, surrealism, pop, graffiti and other art styles. With thematic subjects that touch on current affairs, the bold new works show each prolific artist’s diverse techniques coming together in a new process. The exhibit opens with a reception on Saturday, Aug. 26, at Buddha’s Palm Tattoo Gallery, 313 N. Main St., Sebastopol. 6pm. Free. 707.829.7256.
