The CSUDH/CLA Music Department's Program for the Study of African Diaspora Sacred Music and Musicians has as its primary mission:
- the general study of the life and work of African Diaspora musicians in the field of sacred music, with initial focus upon the musicians of Southern California;
- the special study of the evolution of the Spiritual within the African Diaspora musical repertoire of Southern California; and
- the collection, preservation and performance of this music, to be housed in the Georgia & Nolan Payton Archive of Sacred Music.
The ongoing research of the Program forms the basis for extensive preservation, performance and curriculum development.
