LENOX -- Mozart's ``Don Giovanni" kept 7,649 people up past their bedtime Saturday night at Tanglewood. The magnificent performance by James Levine, the Boston Symphony Orchestra, and a prestigious international cast ended just before midnight. Most of the audience was still there at the close to experience the damnation of the Don, and remained long afterward to cheer the performers.
There were two late changes of cast. Luca Pisaroni , who came in to sing Don Giovanni's servant Leporello , proved a major discovery. The Italian bass is young, tall , and handsome, thereby dispelling many of the tiresome cliches that surround this role. His voice is light, but his singing was lithe, witty, responsive , and imaginative; Leporello became an alter ego for Don Giovanni. Tamar Iveri was fiery as Donna Anna, the aristocratic lady who starts off a very bad day for Don Giovanni -- the last day of his life. The soprano from the republic of Georgia has a gleaming, focused voice that created excitement as it cleaved the air in the vengeance aria. She was skating on thin ice in the second aria, but she managed the spins and turns cautiously. Her pluck earned her a big hand.
