Il Trittico (Metropolitan Opera House, Lincoln Center, performances on Dec. 9 and 12). Patricia Racette, who starred in The Letter, is now playing all three of the soprano leads in Puccini’s triptych of one-act operas. I’m prejudiced, needless to say, so instead of singing her praises, I’ll merely report that the audience burst into very loud shouts of approval after her aria in “Suor Angelica” when I saw the production last week. Jack O’Brien’s staging is decidedly Broadwayish, with megabuck sets to match. Great, great fun (TT).
