Wagner’s breathtaking meditation on love and death holds a unique place in the opera world. Its music has astounded, infuriated, and inspired audiences since it was first heard, and the title roles are acknowledged as among the most extraordinarily demanding in opera. The vocal challenges, the sumptuous symphonic scale of the orchestral writing, and the mystical nature of the story, with its opportunities for creative visual design, make this awe-inspiring work a phenomenon of the repertory.
