Margita in "Das Rheingold" was everything
@alexikeguchi described: the cast was incredibly strong all around, but Margita nearly stole the show. The highlight for me was the scene between Alberich, Wotan, and Loge: the dramatic mastery, voice and acting, was out of this world.
Tonight in "Die Walkure," I was really impressed with Raymond Aceto's acting as Hunding. Stephen Milling is still my vocal high bar for the role, but Aceto was superb. I'm not surprised that Jovanovich had such great chemistry with Mattila, whose voice is still lovely, if not very big, because in the Met in HD in "Rusalka," he had chemistry with two different women. This is either the fourth or fifth time I've seen Grimsley's Wotan, and he really surpassed himself: while he cut his teeth on Wadsworth's production in Seattle and then developed it over the years in Seattle and other opera houses, this production is bringing out the best of him. His Act II monologue was amazing. Even if what he's saying is self-involved, self-important, and self-serving bullshit. (Wotan isn't very bright: he's used to other people doing his arguing for him, and he does not win a single verbal argument with any woman. His confrontation with Fricka was like, Wotan: "I'll give you $20 for that" Fricka: "I won't take a penny less than $50" Wotan: "I won't pay a penny less than $75.")
Star of the show tonight was the title character. I hadn't heard Thoerin live since the early 00's, the Copenhagen Ring was a dozen years ago, and besides the natural effects of aging, sometimes being in demand takes it's toll on the voice, but she was simply the greatest "Walkure" Brunnhilde I've ever seen live. (And I loved Stemme in this production in 2011.)
Now for a rest day of seminars and the Stagehand Ring movie before "Siegfried." Wheeeeee!
