Karita Mattila isn’t my first choice for Tosca, but her Vissi d’arte was extraordinary. Alvarez was also wonderful—the singing both incredibly powerful and achingly sweet. The singer who played Scarpia—fabulous! Loved his snaky jacket. The sets weren’t terrific, but for $20 I wouldn’t think of booing (I might have, had I paid $200). The scene with Scarpia and the 3 women was dumb and out of character—get off his lap and let the devil sing! I thought. Omitting the candles might have worked had there been some visual emphasis on Tosca’s faith (which there wasn’t) or something meaningful in its place (which there wasn’t). All in all, fine singing, fine drama, with just a few glitches--and two way-too-long intermissions--along the way.
