George Balanchine's Rubies

George Balanchine's Jewels is a three-act ballet that uses music from three different composers, which is unusual in its own right. That the ballet has no plot and that all three acts are independent of each other is even more astonishing. "Rubies," the middle act, sets Balanchine's ebullient choreography against Igor Stravinsky's joyous, bouncy "Capriccio for Piano and Orchestra." The dancers, clad in rich red tones, represent the dance of light on gemstones, refracting and bouncing across the stage. The Saint Louis Ballet presents its first-ever performance of "Rubies" as a special Valentine's Day treat. Performances are at 8 p.m. Friday and Saturday (February 15 and 16) at the Touhill Performing Arts Center on the University of Missouri-St. Louis campus (1 University Drive at Natural Bridge Road; www.touhill.org). Tickets are $34 to $59.
