Throughout his lifetime, Polish-born artist Jan Sawka refused to be confined to a single medium—he masterminded the cosmic, 10-story set for the Grateful Dead's 25th anniversary tour; he designed buildings for Arab monarchs; he drew promotional posters and created theatrical sets for productions from Wrocław to Broadway. A student of painting and printmaking in Poland, in his 20s Sawka was the leading artist of the counterculture and the darling of the Polish Poster School. His iconic Solidarity poster sold in the millions, paving the way to his exile in 1976. A printmaker, painter, sculptor, animator, and architect, Sawka worked in New York City for years before moving to High Falls, where he resided until his death in 2012. To commemorate his life and work, the Rosendale Theatre will host a 75-minute show of selected sequential artworks and projected pieces, plus a preview of the forthcoming documentary The Voyages of Jan Sawka. The screening will be held on August 9 at 7:15pm. Tickets are $10 and $8 for members. (845) 658-8989; Rosendaletheatre.org.
