Very briefly noted: I was pretty sure I was hearing the end of Villazon's career last night. Act I he kind of barfed out the first big high note, futzed around with vowels some, left out the last high, and I think maybe took a note or two down. At the end of Act II he strangled horribly on the tenor's big note before the big concertato finish (am I using that right?) and actually stopped singing. He cleared his throat loudly, paused an unbearable couple of seconds, and tried it again, without improvement. It was just simply awful. The act finished. We were told his cover was going on (you know who you are!) and left. Well I'm told by a reliable source he not only went back on, but was "spectacular."
Trebs and Lucia, in my book, not a great match. She was a very gracious colleague to VR and she popped out some nice high notes, but it was largely just a mess in the ways you'd predict. Pitchy, not stylistically idiomatic (and yes, that's a range, but I don't think her singing fell within it), not enough there to be rescued by her presence alone. Kwiecen and Abdrazakov admirably solid. Another good Arturo in Colin Lee.
