A series of exhibitions and performances about violins recovered from the Holocaust begins next year at the University of North Carolina at Charlotte in a premiere of the instruments in North America.”Violins of Hope” is a collection of 18 instruments restored by Israeli master violin maker Ammon Weinstein, who began collecting and restoring them in 1996. Some were played by Jewish prisoners in Nazi concentration camps while others belong to the Jewish Klezmer musical culture, which was all but destroyed in the Holocaust.The violins were first played publicly in 2008 in Jerusalem and then were exhibited and played last year in Switzerland. They’ll be at UNC Charlotte next April, which will mark their first appearance in North America.
