When the Ayatollah Ruhollah Khomehni banned all music in Iran and declared it to be sacrilegious, his views by no means reflected the outlook of all Muslims. In fact, Islam's Sufi sect believes music to be a sacred and necessary element of spiritual life. Like Hindus, the Sufis passionately encourage meditation, dancing and chanting. Nusrat Fateh Ali Khan is a master of traditional Qawwali, the music of the Sufis. Soulful and hypnotic, Khan's passionate singing on these songs of praise underscores the richness and vitality of Sufi culture. While Qawwali music goes back centuries, the use of synthesizers adds a modern edge to the highly absorbing Mustt Mustt.
