This recording is the chorus of Tzur Mishelo. It is often sung before Birkat HaMazon (Grace after Meals) on Shabbat. It is sung in the tradition of the Spanish-Portuguese Jews from Florence Italy.
Many of the Jewish communities of Italy were founded by Spanish and Portuguese exiles after the expulsion in 1492 and 1497. They were also augmented by former Conversos/Anusim who fled there.
