When you’re born and raised in the vast expanse of the American West, it can be easy to overlook the grand scale of our natural surroundings. British-born and San Francisco–based artist Richard T. Walker doesn’t have that problem, and he brings a new perspective to the varied landscapes of the West with the first Bay Area exhibit of his equally varied art when di Rosa presents “The Fallibility of Intent” exhibit this month. Walker looks at the vast deserts, towering mountains and otherworldly forests of this region through photography, video, music, performance and sculpture installations with work that’s heralded for its complex explorations. “The Fallibility of Intent” exhibits through April 26, and opens with a welcome reception on Saturday, Feb. 7, at di Rosa, 5200 Sonoma Hwy., Napa. 6pm. Free. 707.226.5991.
