Kristine Opolais stars in a new production of the opera that first won her international acclaim, Dvořák’s fairy-tale opera about the tragic water nymph Rusalka. Sir Mark Elder conducts Mary Zimmerman’s new staging, which also stars Brandon Jovanovich as the human prince who captures Rusalka’s heart; Katarina Dalayman as Rusalka’s rival, the Foreign Princess; Eric Owens as the Water Sprite, Rusalka’s father; and Jamie Barton as the duplicitous witch Ježibaba.
