Muslim Roots, US Blues

Written by Jonathan Curiel

Sylviane Diouf knows her audience might be skeptical, so to
demonstrate the connection between Muslim traditions and American
blues music, she'll play two recordings: The athaan, the Muslim call
to prayer that's heard from minarets around the world, and "Levee Camp
Holler," an early type of blues song that first sprang up in the
Mississippi Delta more than 100 years ago.
