This is Sandy Brown Jensen, and you’re listening to Viz City, KLCC’s arts review program. Imagine a watercolor painting that captures the raw power of the Oregon Coast. A towering wave crashing against the rocks, a serene tide pool teeming with life, or the golden glow of a sunset over the dunes. These are the breathtaking scenes brought to life in the “Pacific Threshold” exhibit at the Giustina Gallery at the LaSells Stewart Center at OSU in Corvallis.
