The soloist was the lyrical, incisive Alisa Weilerstein, who released a flawless recording of the concerto with the Czechs several years ago. Although there was a bit of push-and-pull between her and Mr. Bychkov during the opening Allegro, they eventually settled comfortably into an excellent performance that displayed just how beautifully Ms. Weilerstein can make her instrument sing, and how skillfully this nimble orchestra can deal out dances, fanfares and yearning melodies in quick succession.
