Magnificent singing, orchestral playing, and conducting. And of course the music is sublime. But the staging, much of it, is absurd. Wagner audibly groaning in his grave. When directors (François Girard, in this instance) radically "interpret" a work to make an individual, narcissistic statement, blithely disregarding and contradicting some of the basic features envisioned by its creator, things can go amiss, as they do here in the third act. Schade.... But of course seeing it live in HD is better than actually being at the Met itself.
