Very interesting report, thanks for the firsthand! I know very little about opera but I had read a review in the New Yorker (I'm linking it here (http://newyorker.com/critics/music/?040809crmu_music1), but I don't know if it will work), which left me intrigued, though not in a good way. (The critic, Alex Ross, ripped it to hell -- and though I know little about opera, I like Ross's writing so, however irrationally, I tend to trust his views!) I might have told you, I've got a Buffyverse plot bunny about the Fanged Four going to the premiere of "Parsifal," but I'd have to do a lot more research before I was ready to write it :).
