Two new exhibits open this weekend at Waterfall Arts, located on High Street in Belfast. A reception will be held from 5 to 8 p.m. Friday, Oct. 2, during the First Friday Art Walk, to debut both “Empty Walls and Windows” and an exhibit centered around the annual Belfast Poetry Festival. “Empty Walls” is a new project of Maine artists who have stepped outside the conventional gallery system and filled open spaces around towns and cities with their work. The idea is to hang art all over the place, in windows, on empty walls and in closets. With some empty walls of its own, Waterfall Arts was eager to give the artists a chance to try this idea. All the work exhibited is for sale, and the artists decide what pieces they will hang, with new work going up every few months. Artists now showing in the Corridor Gallery include James Fangbone, Lynn Harwood, Barbara Sullivan, Wally Warren, John Bozin, David McLaughlin, Abby Shahn, Robert Saunders, Dan Beckman, Alan Crichton, Stu Silverstein, Craig Becker, Norm Tinker and Ted LaFage. The poetry exhibit will open in the Fallout Shelter Gallery, and features visual and verbal collaborations between artists and poets, part of the annual Belfast Poetry Festival. Belfast poet Karin Spitfire and Portland artist Brian Reeves created an interactive piece inspired by each other’s ideas. The other team is Solon artist Abby Shahn and poets Stephen Petroff from Topsham and Mark Melnicove of Dresden. An anonymous found photograph (above) of schoolchildren from what appears to be the early 20th century is the departure point of their numerous and varied pieces in the show. Other artist-poet collaborations are on display at galleries and venues throughout Belfast. For more information on the Belfast Poetry Festival events, visit www.belfastpoetry.com. Gallery hours are Tuesday through Friday from 10 a.m. to 5 p.m., and Tuesday nights until 7 and by appointment. For more information, call 338-2222 or visit www.waterfallarts.org.
