The CCN/Aterballetto presents a true concert in dance. Rhapsody in Blue by Iratxe Ansa and Igor Bacovich is a playful, vibrant choreography, much like Gershwin’s iconic score. In An Echo, A Wave by Philippe Kratz, the flowing movement of the two dancers evokes the motion of the sea. Reconciliatio is a delicate female pas de deux by Angelin Preljocaj, set to Beethoven’s Moonlight Sonata. Solo Echo by Crystal Pite, through Brahms’s sonatas for piano and cello, invokes winter to express something essential about acceptance and loss.
