I thought this was a great concert. I love this opera, and have seen it either 3 or 4 times before, so I was pretty well oriented, but I definitely agree that they should have at very least had a decent synopsis in the program and, preferably, titles. With extremely rare exceptions, no one can understand opera as sung, even when it's in your native language.
I'm on the fence about the Prologue, which I found a bit long, but well-intentioned. I don't think it was necessary, or really added that much to the event, but it didn't bug the hell out of me. Yes, a few of the contempo references were more smart-assy than smart.
But the two ladies impressed me very much. Strong on all counts—voice, acting, and movement. The staging started off well and seemed to get even stronger in the second half. Soriano's splashiest gown for the Sorceress was great fun (in the right way, as opposed to some of the Proloque, which seemed fun in the wrong way.)
This was probably my favorite live version I've heard, and that's saying a lot since I wasn't going in expecting them to capture the spirit, vigor, and heartbreak of the piece so well.
