Don, did you read any reviews of this series of performances online? They weren't all complimentary, one suggested Voight's Brunnhilde was "swinging at the high notes." I wouldn't say that, but I haven't listened to multiple performances to compare, and what I heard was lovely. In the stage and costume design department I will note that it's amazing the spark a bright red wig adds to the character (you'll note over the course of the performances that her hair gets a bit darker with each opera, kind of like Grace Kelly's garments in Dial M for Murder).

She herself in an interview said that as the first time she's played Brunnhilde it isn't as "fully fleshed out" a performance as it would be with successive performances, given time to consider the part with the eye of experience.

And this weekend I think you'll really enjoy Sigmund and Siglinda. :)
