Tune in this afternoon and evening to hear the glorious Gil Shaham on record and in concert. The Israel-born, Illinois-bred violinist leads the International Sejong Soloists in Mendelssohn's Octet - surely the greatest work ever written by a 16 year old - on Barney Sherman's show. Then, on Performance Today, he plays the Butterfly Lovers Concerto, written in China in 1959. When a friend introduced him to the work a few years ago, his friend burst into tears because the music was so emotional. Hear Shaham play it, and see if it moves you, too.
