Nadia Salerno Sonnenberg (Nadja Rose Catherine Salerno Sonnenberg) is an Italian violinist born on January 10, 1961 (Perlman was 15 years old.) In 1969, she and her family came to the U.S. from Italy and settled in New Jersey. She had been a pupil of Marianna Gabbi as a very young girl but afterward studied at the Curtis Institute and later on with Dorothy DeLay at the Juilliard School of Music. She is known for her uniquely idiosyncratic and iconoclastic style - somewhat like Nigel Kennedy. She wrote her autobiography in 1989. There are several videos of her on YouTube and she has already recorded most of the standard repertoire. Sonnenberg is currently the Director and Concertmaster of the New Century Chamber Orchestra based in San Francisco. The NCCO currently has several recording and performing projects underway. Perhaps for that reason, she does not have many concerts scheduled with major orchestras in 2010.
