Bela Bartok left only outlines for his viola concerto, but the piece, which was constructed from these outlines is very beautiful and allows the sloloist to display both virtuosity and expression. Ori Kam, 24 years old, replaced Nabuko Imai, but stole the show. If we have such a violist in Israel, why look elsewhere? From the first contact of his bow on the string a broad, penetrating and pleasant sound eminated. I expected, naively, that the audience would demand to hear the final movement again, but alas I was disappointed.
