New exhibits “Fermentation” and “Lexicon of Sustainability” will open with a Fourth Friday Art Walk gala reception July 24 from 5 to 8 p.m. at Waterfall Arts, 256 High St.

The Clifford Gallery will be teeming with art inspired by the process of fermentation in its many forms — paintings, assemblage, interactive sound art, photographs, sculptures, videos, and dance depicting bountiful, unstoppable energy of all kinds. Everyone is welcome to attend the opening, and sample fermented goodies provided by the Belfast Coop, Marshall Wharf Brewery and others. A poetry reading and dance performance is scheduled to begin around 6 p.m.

On the same night, the “Lexicon of Sustainability” pop-up art show featuring visual narratives exploring key sustainable food terms like “food miles” and “edible school yards” will open in the Corridor Gallery. Part of a national effort, the show generates community dialogue about key terms in sustainable farming to help strengthen local food systems. Jolene Blais and her UMaine Orono students have participating in bringing the “Lexicon” to Maine locations; the show at Waterfall Arts highlights links to the Belfast Farmer’s Market and the “Fermentation” exhibit.

Artist Lesia Sochor had the idea for an exhibit based on fermentation for a number of years before she began working with the program committee at Waterfall Arts to bring it to fruition. Artists were paired with fermenters who make bread, beer, wine, cheese, kimchee, sauerkraut and other products for inspiration and direction. More than 20 artists will show the results of their collaboration. Artists, fermenters, presenters and performers include Russell Kahn, Lynn Karlin, Mark Kelly, Lesia Sochor, Joan Proudman, Kenny Cole, Mary Boothby-Thomas, Martha Piscuskas, Abbie Read, Linda Stec, Susan Smith, Susan Perrine, David Jacobson, Shannon Brown, Tom Luther, Larraine Brown, Elizabeth Garber, Katenia Keller, Lisa Newcomb, Frank Giglio, Bennet Verbeck, Ana Antaki, Derek Smith, Kathy Goddu, Simon and Jane Frost, Phoebe Chase, Christian Koebl, Betsy Garrold, Eric Rector, Roy Curtis and Zafra Whitcomb.

Both shows will run through Sept. 11. Hours through August are Tuesdays through Fridays from 10 a.m. to 5 p.m.; Saturdays from noon to 4 p.m.; and by appointment (call 338-2222 to arrange).

Food fermentation demonstrations, talks and other related events will be held in August; consult waterfallarts.org for times and details. The exhibits are sponsored by the Belfast Coop, Seebreeze Eye Care, Sam Mitchell, Marshall Wharf Brewery, the Maine Arts Commission, an independent state agency supported by the National Endowment for the Arts, and yearlong sponsor Revision Energy.
