Las Hermanas, first performed in 1963, was the first of six works that Kenneth MacMillan made for the Stuttgart Ballet. It is based on Federico García Lorcaís 1945 play La casa de Bernarda Alba and set to Frank Martinís Concerto for Harpsichord and Orchestra.
MacMillan creates a powerful exploration of sexuality, repression and familial jealousy. The sisters' contrasting temperaments are communicated through their movements: the eldest, introverted sister dances with clenched fists and her pas de deux with her fiancé is rigid and inhibited. By contrast, the sensual younger sister dances with abandon. MacMillan pushed classical choreography to new limits with Las Hermanas, not least in its shocking final scene. Nicholas Georgiadis's stark, prison-like set and Frank Martinís score combine to create an atmosphere of unsettling claustrophobia.
