The spring season heats up with Boston Ballet’s latest production, Kylián/Wings of Wax, which comes to the Boston Opera House March 23–April 2. Centered around the title work (pictured)—a sensual piece set to the music of Heinrich von Biber, John Cage, Philip Glass and Bach that is danced underneath an upside-down tree—by acclaimed Czech choreographer Jíři Kylián, the program also boasts the 1960 classic Donizetti Variations from ballet giant George Balanchine and the playful Cacti from young Swedish phenom Alexander Ekman, which is punctuated by music from such famed composers as Haydn, Beethoven, Schubert and Mahler.
