Massachusetts artist Ian Kennelly will use his Glen Arbor Arts Center residency to “further his observations” of the ephemeral space that exists where water, land and sky meet. Kennelly will talk about his project during a free public presentation on Friday, Aug. 25, at noon, at the GAAC, which also bids farewell to summer with a Front Porch Concert on Aug. 25 from 5-7 pm. The Arts Center also hosts Sarah Shoemaker for a Coffee With the Authors event on Aug. 26, a A guided walk-and-talk of “In Translation” on Sept. 2, and a screening of the film “Plague Phase” on Sept. 7.
