With an emphasis on emotional expression over figurative representation, abstract art is a long-evolving movement that is increasingly finding a global audience. This week, Sonoma County gets a major dose of today’s hottest artists in the field when ‘Purely Abstract: Visions in Line, Form and Color’ opens in Healdsburg. Artist Jerrold Ballaine and art historian Satri Pencak juried the show, featuring works from over 50 artists, including locals like Sonoma’s Shotsie Gorman and Santa Rosa’s Max DuBois. The exhibit opens with a reception on Saturday, April 28, at the Healdsburg Center for the Arts, 130 Plaza St., Healdsburg. 5pm. Free admission. 707.431.1970.
