“Continuous Replay: The Photographs of Arnie Zane,” the first comprehensive survey of the late artist’s work, receives an energetic opening Saturday as acclaimed dancer and choreographer Bill T.

Photographs of the California desert, taken between 1911 and 1950 by the Automobile Club of Southern California, document the evolution of what once was considered a region to be avoided.
