Curated by Laurie Bogdan and Kimberley Harding; Hapgood Wright Town Forest in Concord, MA, September 1 – November 14…The Umbrella site 2021 Art Ramble: “Something in the Air” lists the sixteen artists’ bios, websites, and statements about their artwork, as well as audio versions to access as you move along.I visited in September and October, followed by posts, each focusing on four installations. This third post connects four more through their relation to the forest’s trees, shadows, and light while always aware of the air.
