Here is an excerpt from Wilcken's book Drums Of Vodou:
Vodou, commonly knows as “voodoo,” is a widely discussed but little understood religion. In this book author Lois Wilcken discusses politics in Haiti, anti-Vodou campaigns, plus the religious and cultural context of Vodou. But the chief contribution of this landmark book lies in its presentation and analysis of the sacred music of Haiti. Guided by the great Haitian master drummer Frisner Augustin, the author reveals the sacred rhythms of spirit possession. This book appeals to a wide range of percussionists, Caribbean music enthusiasts, scholars, and those interested in Vodou or neo-African religions.
