Dangerous mission

In his show at the Maud Morgan Fine Arts Chandler Gallery, in Cambridge, Mass., Mr. Bergstein shows how he has used his studio floor as "an archaeological site in which to explore my own mind."

The gallery says that "For over a decade, he has added paint and collage to an ever-evolving studio installation that serves as a figurative and literal starting point for his artwork. The pieces ... combine photographs of his studio collage with additional visual elements, intentionally blurring the lines between photography, painting and collage.''

Self-exploration can be the most traumatic exploration of all.
