Bambasa Street leads into a poor, gang-controlled working-class neighborhood of the port city of Karachi in Pakistan, where particularly descendants of African slaves and sailors reside. Here, in "Karachi's Harlem," beats the heart of the wild cosmopolitan megacity, a place of vibrant vitality, enthusiastic playfulness, and ecstatic music and dance. At the center of this ethnographic, dense narrative is a magical healer and shaman. His domain is the intermediate world of spirits, demons, and other invisible beings, with whom he connects in trance rituals to appease and ward off. An authentic depiction of the environment and at the same time a book about the religious underground of Islam.
