A new art gallery has opened in Montpelier with a provocative inaugural show. The Susan Calza Gallery is across Main St., from Kellogg-Hubbard Library and the first exhibition is an installation work entitled “Domestic Disasters.” Susan Calza is a multimedia artist who was a faculty member at Johnson State College until 2014. Calza’s opening show focuses on gun violence and in particular mass shootings. There were 340 mass shootings in the U.S. in 2018, and Calza represents each of those shootings with a small tag dangling from the ceiling on red ribbon and surrounded by gold AR-15 bullet casings. The tags are for sale at $10 each. Calza says she’ll donate half of the proceeds to organizations working to prevent gun violence. There is an opening and artist talk on Sunday from 2-4:30 p.m.
