Yaakov Zahtz (R), son of Congregation Bnai Yeshurun’s Rabbi Ari Zahtz, made his debut appearance on guitar in the sukkah of Teaneck’s Bennett & Tammi Schachter at a beautiful kumzitz and siyum that  took place this past Motzei Shabbat. To the left of Yaakov Zahtz are Jewish music stars Ari Boiangu, Simcha Leiner (with microphone), Neshoma Orchestra’s Dov Katz, and Shim Craimer on keyboard.
