Colorado artists began embracing abstraction in the 1930s, and by the late '40s and early '50s, it had become a full-blown regional movement. Unfortunately, much of the work has been mostly forgotten. Aiming to correct this oversight, painter and volunteer art historian Tracy Felix put together Colorado Modernism, a handsome and well-thought-out show. It was filled with gorgeous mid-century-modern paintings by the likes of Vance Kirkland, Charles Bunnell, Mary Chenoweth and Al Wynne, along with solos devoted to photographer Jim Milmoe and sculptor Bob Mangold. A trip to Golden to see this tremendous show was the best mini-vacation you could have taken last summer.
