The Sam Roloff Abstract Retrospective, a look at the artist’s works from 2009 to 2014, kicks off this First Thursday with an opening reception at White Space (1439 NW Marshall St.) from 6 to 11 p.m. “I define many of my paintings as time capsules,” says Roloff. “Many of my artworks have 10 or more layers beneath the surface, indicative of the passage of time and the creative process, which are meticulously documented. “Like time and music, my work has movement that leaves a trail of evidence beneath layer upon layer of oils, wax, and glistening resins. Each series that I develop expresses the reality that each of us as individuals—and as citizens of communities, cultures, and nations—has a unique back-story that informs our present, even if only traces remain of what came before. “When collectors purchase one of my paintings, they are actually purchasing a multi-layered collection of all the paintings and scenes within their many layers of imagery, symbolism, ideas, and emotion. The crux of this approach harkens to the tradition of what the Italians call pentimenti: the ghosts of images hidden beneath a painting’s surface.” Pictured above: Equal Rights Marriage Comes to Oregon by Sam Roloff.
