“A Delicate Balance,” an ongoing free public art exhibition in Sonoma Plaza, will run through Oct. 19 and is hosted by Sonoma Valley Museum of Art in partnership with the City of Sonoma. “The sculptures explore the equilibrium between fragile and solid, nature and technology, humankind and science,” says SVMA executive director Linda Keaton. “So it’s sort of a reminder of the delicate balances of life and about how our world has changed over the past year as well.”
