Baroque encounter with violinist Mutter is thoroughly engaging

Symphony Center, Chicago: With the 17-piece Camerata Salzburg chamber orchestra accompanying her at Symphony Center, it was an all-Baroque encounter with familiar friends J.S. Bach and Giuseppe Tartini. It helped that some new artistic blood was brought into the mix. In Bach's Concerto for Two Violins in D Minor, BWV 1043, the 21-year-old Vilde Frang joined Mutter onstage. This young Norwegian recently got a taste of major league exposure last year in a successful collaboration with the London Philharmonic at Royal Festival Hall.
