Born in México, Rubén Grez is a traditional Jewish and hasidic singer. He has recorded two solo albums: Homenaje a la Liturgia Judía y al Espíritu Jasídico around 1985 with arrangements by Laszlo Rooth and orchestrations played by La Orquesta de la Ópera de la Ciudad de México. The album was later reedited and remastered in 2007 with the help of radio journalist Uriel Waizel; and Homenaje a la Canción Judía with arrangements by piano master Rufino Montero, with whom he also shares a choral group, Voces de Encuentro, with members of the Mexican Jewish community, that revisits and interprets the traditional Mexican songbook from the 20th Century, specially the compositions by Mexico City urban poet and chronist Chava Flores.
