Shaul Blecharovitz
Shaul Blecharovich came from a family of cantors (his brother, Avraham Blecharovich, was a well-known cantor in Argentina). He conducted the Yoel Engel choir of forty choristers who sang oratorios, cantatas and folk songs in Hebrew and Yiddish in Kovno (the soloist was Yona (Anna) Warshavski).
He studied music at the Reali Hebrew high school in Kovno. During the war the family wandered around U.S.S.R. and he was employed by the Red Army Choir. After the war, he returned to Vilna which was then the capital of Soviet Lithuania. In 1956 he founded the Jewish folklore choir "Anahnu Kan" (We are here) in Vilna, with the help of his daughter, Aliza; he was its first conductor and the members of the choir made aliyah in 1971. The choir became famous in 1970 with the song Kahol Velavan (Blue and White). The song was written by Israel Rachel (who made aliyah in 1971) and became the anthem of protest of the Jews of Silence – the Russian Jews who sought permission to make aliyah to Israel.
His two children, who made aliyah in the 70s, are both musicians. His daughter Aliza Blecharovich-Goldberg is a choirmaster and singer who conducted the Anahnu Kan choir. His son, Moshe Blecharovich, a composer, does musical arrangements and management; he is also a conductor and pianist. Most of his work is connected to music for the theater. Moshe's sons are also musicians: Shahar Blecharovich is a saxophonist and Tal Blecharovich is a singer-songwriter.
