Halloween night, Di Rosa opens a show of artworks related to the mystical, the transcendent and the transformative.

“Altered States: The Collection in Context” will be at the Gatehouse Gallery through Jan. 23.

“It’s a diverse show,” said curator Chandra Cerrito, who said the theme encompasses, “spiritualism in its broadest sense.”

Works range from artists making comments on spirituality to “manifestations of spirituality,” she said. Photographs, paintings, sculpture, an electronics piece, kinetic sculpture, along with “art works that cross over between sculpture and painting,” are part of the show, she said, “along with a couple of pieces made for the show — one made of sugar and painted strips of aluminum that are collaged together.”

Curator Chandra Cerrito said the theme was in place when she was invited to put the show together. “This is the first show I’ve ever curated that I was assigned a theme, but I was happy to do it because it’s a personal interest of mine.”

 She began work on the show by reviewing slides of the 2,000 to 3,000 works in the di Rosa collection, but the final show also includes works by new artists as well as new works from artists who have other pieces in the extensive collection begun by Rene di Rosa of works from Bay Area artists that is housed on a 217-acre preserve in the Carneros region.

“You could interpret the theme in different ways,” said Cerrito, a Napa resident who is an artist as well as a curator and arts consultant. “I’m drawn to works that are minimal, meditative. I selected works that seemed to be a reflection of a spiritual experience.”

The works include some “witnessing a spiritual experience,” she said, like photographs of shamans or a Buddha carved into a tree trunk. “Some of the artists I introduced practice mediation and this reflects in their work — they’re creating something that can be meditated upon,” she added.

Artists included in the exhibition are Lynne-Rachel Altman, Jim Campbell, Bruce Conner, Linda Connor, Lewis deSoto, Robilee Frederick, David Ireland, Keira Kotler, Thérèse Lahaie, Richard Misrach, Robert Moon, David Simpson, Travis Somerville, Elisabeth Sunday, Michele Théberge and Darren Waterston.

Cerrito will be leading a panel discussion with some of the exhibiting artists at di Rosa on Dec. 2 at 7 p.m.
