Peter Eötvös’ adaptation of Chekhov’s classic 1901 play Three Sisters captures much of the source material’s stultifying atmosphere, nervous tension and bone-deep sense of regret. The libretto, written by the composer in collaboration with Claus H. Henneberg, takes apart Chekhov’s chronology and, in a prologue and three sequences, gives equal attention to the plights of Irina, brother Andrei, and Mascha. Events are seen Rashomon-like, powerfully bringing us closer to the motivations and preoccupations of Chekhov’s unhappy folk.
