Sonnambula unpeels Bellini’s mysterious La Sonnambula, zooming into the opera’s central role of The Sleepwalker in a sensorial meta-journey. Her descent from clarity to confusion is channeled by a live vocalist, who herself is gradually subsumed by the voice of Guiditta Pasta, the diva who premiered the role in 1831. Sonnambula plays out on ever-larger scales, with miniature scenery, destructible puppets, and two choric dancers in an environment of light, sound, and smell.
