The Tefillalt Ensemble: Established in 1998, the members of the Tefillalt ensemble – Yair Harel, Nori Jacoby and Yonatan Niv – gathered during their study with Israeli composer/educator Prof. Andre Hajdu in Jerusalem. They are also original members of the Jerusalem ensemble of contemporary music Haoman Eighteen, an Israeli counterpart to the Radical Jewish Music projects of New York city. This group collectively produced in 2004 (on behalf of the Israel Festival) the now internationally acclaimed show Kulmus ha-nefesh (Writing from within) based on ancient Habad Nigunim.
