From an anonymous observer:
Jackie Evancho appeared to have held her own today in the reasonably rich company of Dimitri Hvorostovsky and Sumi Jo at the ”Bouquet of Opera” concert in Palace Square, St. Petersburg, Russia. Sarah Hicks conducted the symphony orchestra that accompanied the trio.
While at first quite reserved in his opinion regarding Jackie (and young performers in general) during interviews these past few weeks, at one point Dimitri was hugging Jackie in the wings, and literally threw her back onto the stage for a second bow after one of her performances.
When Sumi Jo and Jackie performed a duet of Con Te Partiro, it was first difficult to differentiate who was who––except that the younger voice proved to be the smoother of the two.
Each performance left a smile on this viewer, and by the applause, the
entire audience as well. In spite of high winds, chilly temperatures,
and a succession of motorcycles demonstrating the need for effective
mufflers, this was a concert to be remembered, and perhaps repeated in
more favorable locations.
UPDATE: Here is a Russian report of the concert from Ria Novosti.
