“Hybridity: The New Frontier” is 21c’s latest group show, an exhibition that’s part of the Arts and Cultural Attractions Council’s 2015 YES! Fest that focuses on the environment. It is a display of hybrids, as in “nature meets technoculture and the new natural is both organic and manufactured.” The videos, paintings, sculpture and photographs have a sense of the “Island of Dr. Moreau” to them, plus the landscapes are not as pastoral as they first look. “During these periods of significant concurrent economic, technological and socio-political change, hybrids embody fear and desire, the known and the unknown,” the exhibition explains. “They and the territories they may inhabit belong to the uncanny, a place eerily alien and familiar at once.”
