While many choreographers would look to a 50th anniversary tour to program a greatest hits package, Twyla Tharp, who will be at The Granada Theatre tonight, does the opposite in a career of bold moves. Instead she’s created an evening of two new works. “Preludes and Fugues” raids the extensive pieces in J.S. Bach’s “Well-Tempered Clavier” and bears the influences of all those that came before her in modern dance: Merce Cunningham, Jerome Robbins, Martha Graham and George Balanchine. And “Yowzie” turns from classical to jazz, with bright costumes and a soundtrack of early ragtime and jazz.
“Preludes” is “the world as it ought to be,” she says, “and Yowzie is the world as it is.” Ms. Tharp is quoting herself, and it’s a phrase that graces the evening’s program in her artistic statement. That tension between fantasy and reality has long been part of her work.
