A youtube sample from Cancion Sefardi.

From WQXR website: "Joined by his wife and collaborator, soprano Montserrat Figueras, as well as the musicians of his own ensembles, Hesperion XXI and La Capella Reial de Catalunya, Savall charts Jerusalem's history from 1200 BC to the present day..The performance comes at a time when Israelis and Palestinians are at deep odds over political borders and settlement activities in East Jerusalem. But as the liner notes to the lavish 2008 recording of Jerusalem explain, etymologists have translated the Hebrew name Jerusalem as "the city of the two peaces," a reference to both "heavenly peace" and "earthly peace." The former was proclaimed by the prophets who lived in or visited the city, while the latter was sought by the political leaders who have governed the city throughout its five thousand years of documented existence."
