Turned away from the Ron Shulamit Conservatory because he was too small to handle a violin, the three-year-old Itzhak Perlman taught himself on a toy fiddle. Now, of course, he’s one of the greatest musical prodigies of our time. Onstage, Perlman communicates an irresistible joy of making music, while offstage, he is beloved for his charm and humanity, and a recent New Yorker piece uncovered Perlman as a closet comedian in the Borscht Belt tradition. Having appeared with every major orchestra, and in recitals and festivals around the world, the reigning virtuoso of the violin isn’t one to miss on Saturday, Sept. 21, at the Green Music Center. 1801 East Cotati Ave., Rohnert Park. 6pm. $55—$125. 866.955.6040.
