The musical culture of Haitian Vodou, long shrouded in an aura of black magic, is brilliantly unveiled in this recording. Largely recorded in the field, both urban and rural Vodou ceremonial music are captured with state-of-the-art fidelity. The CD is accompanied by photographs, essays, interviews with Vodou practioners, poems, proverbs, folk tales, and more.
Various is the correct author for any book with multiple unknown authors, and is acceptable for books with multiple known authors, especially if not all are known or the list is very long (over 50).
If an editor is known, however, Various is not necessary. List the name of the editor as the primary author (with role "editor"). Contributing authors' names follow it.
Note: WorldCat is an excellent resource for finding author information and contents of anthologies.
