Internationally acclaimed cellist Yo-Yo Ma has described violin virtuoso Artruo Delmoni as "an enormously gifted musician and an impeccable violinist. His playing style is unique, and his gorgeous sound is reminiscent of that of great violinists from a bygone era." Your chance to hear Delmoni perform the Beethoven Violin Concerto with the Vermont Philharmonic is this weekend: Saturday, May 2 at 2 pm at Chandler in Randolph; Sunday, May 3 at 2 pm at the Barre Opera House.
