Voices and Faces of the Adhan: Cairo
The city of Cairo has 4,000 mosques. At least that's the number officially recognized by the government.
But there are more like 30,000 if you count all the other places where people gather to pray. And there's a person, known as a muezzin, who calls them to prayer, five times day, everyday of the week. Anna Kipervaser fell in love with the sound when she took a trip to Cairo.
Now she's in the process of producing a documentary called "Voices and Faces of the Adhan: Cairo," about the muezzin. She says that she was simply inspired by the sound.
