New York metal sculptor Albert Paley is a master metalsmith who constructs massive, intricate and imaginative pieces that speak to man’s relationship to the natural environment. This summer, nine of Paley’s largest works are on display throughout downtown Sonoma, and many more can be seen in the exhibit ‘Albert Paley: Thresholds.’ The extensive installation is Sonoma’s largest public art event, and docents will lead visitors on walking tours in the coming weeks. This weekend, the summer-long show opens with a reception on Saturday, July 1, at Sonoma Plaza (First Street East, Sonoma; 2pm) and the Sonoma Valley Museum of Art, 551 Broadway, Sonoma. 5pm. 707.939.SVMA.
