Widely acclaimed violin virtuoso, conductor and instructor Itzhak Pearlman, will be performing the Bach Violin Concerto #2 this evening at Davies Symphony Hall.  My daughter asked me if I, like J.S. Bach, would walk 200 miles to hear a great violinist play?  I responded that I wouldn’t trudge the 200, but would brave the Bay Bridge at the 6pm rush hour and meet my buddy Steve Shoen at Ruth Chris Steakhouse for a cocktail before the concert.  My, have times changed.
