With its banquet of four Bay Area premieres, Chicago’s Joffrey Ballet came on looking like the old Joffrey Ballet Saturday, Nov. 18, at Berkeley’s Zellerbach Hall. That was a good thing. That the troupe now dances at a technical level unachieved in his time by co-founder Robert Joffrey is an even better thing. Credit community support in the Windy City and a decade under artistic director Ashley Wheater, a former member of both the Joffrey and San Francisco Ballets, for imposing high standards on an ensemble which always possessed spirit aplenty, The three-residency arrangement inked with the Joffrey by Cal Performances will spread over five seasons and we will watch the company evolve.
