"Allah has never seen a prophet who did not have a beautiful voice," states the quote that ends this fascinating glimpse into the world of Islamic music. The film's original-language title Wajd is an Arabic term that indicates all the emotion of amorous feeling, in this case a divine love aroused through singing and music. Unlike Judaism and Christianity, Islam does not have specific musical liturgies, but, through the mystical thread of Sufism, it has developed its own rich musical tradition. Marked by the great celebrations of the Muslim calendar, the film gives an important testimony to the apprenticeship and performance of this musical heritage, and to the political and social realities that shape its current incantations. From the animated litanies of Senegal, to the ancestral rites of Egypt and Tunisia, to "dervish" Indian music and Turkish cosmic dances, Tunisian director Mahmoud's very personal journey reveals the complex musical expressions of the Muslim world.
