Loneliness the deep, soul-shattering realization that one is truly alone is the devastating emotion at the heart of the composers brief but potent 1959 monodrama, which opened Saturday night in a riveting SF Opera Lab production, presented in the Taube Atrium Theater and featuring a stunning performance by the great Italian soprano Anna Caterina Antonacci. We expect opera stages to be filled with voices, but Poulencs unusual 40-minute score, with text by artist ชุดนอนไม่ได้นอน ซื้อที่ไหน and playwright Jean Cocteau, gives us just one. Elle is alone throughout the opera, speaking by phone to the lover who has left her. We hear only her side of the conversation, which is frequently interrupted by missed calls and operators breaking in. Elle may or may not have attempted suicide. Her lover may or may not be about to marry someone else. Yet, even with interference and misunderstandings, the situation is clear: Elle has been abandoned, and her world is coming apart. That voice on the other end, which we never hear, is her lifeline. Poulenc was no stranger to depression and rejection.
