Fans of classical ballet, rejoice: the Staatsballett takes a break from doing director Nacho Duato’s choreography to return to an even older chestnut – George Balanchine’s Jewels. It’s a full-length ballet, but it’s also abstract, tracing different forms in each of the three sections. “Emeralds” to the music of Fauré is lyrical and romantic; “Rubies” set to Stravinsky is a little fierier. It rounds off with Tchaikovsky, “Diamonds”, in a nod to Balanchine’s training with the Ballets Russe. This staging features new costumes, which will, true to the namesake, dazzle.
