Cantors' Concert Mann Auditorium, Tel Aviv June 21 For people who enjoy listening to a talented cantor in synagogue, hearing any of the cantors who sang sacred music for the three festivals at Tel Aviv's Mann Auditorium on Wednesday would have been satisfying enough to say "dayenu." But a packed audience got to hear not one, but four world renowned cantors: Ya'akov Motzen of Toronto, David Propis of Houston, Texas, and Yitzchak Meir Helfgot and David Weinbach of Israel. They were joined by the Israel Philharmonic Orchestra conducted by Dr. Mordechai Sobol and the cantorial choir of the Yuval Israel Ensemble for Chazanut. Each cantor performed several pieces on his own from the Pessah, Succot and Shavuot prayers. But the highlight of the evening came when they united for performances of "Retzei" and "Shir Hama'alot." The latter tune was made famous by the late great Yossele Rosenblatt, whose 73rd yahrzeit was marked at the event. The "Shir Ham'alot" finale was even more appropriate because its text is found in the grace after meals, and the concert was indeed of a feast of music.
