Curated by Thunder-Sky, Inc.’s co-founder, Bill Ross, the exhibition depicts two possible visions of the future: a gory nightmare of blood and zombies imagined and co-created by Adams & Brandehoff, and Lambert’s pristine vision of a future devoid of human contact. Ross sets up this binary within Semantics’ two highly patinated gallery spaces, and the gallery might be just the perfect place to be to imagine the end of the world. Reception 7-11 p.m. Saturday, Nov. 3. Semantics Gallery, 1107 Harrison Ave., Brighton. semantics-gallery.com, thunderskyinc.org.
