Cajun music is a generic term to refer to the music of French South Louisiana.
There is no better source of information that the bilingual book, "Musiciens cadíens et créoles; The Makers of Cajun Music," by Barry Jean Ancelet, a well-illustrated large-format volume printed by the University of Texas Press. Ancelet was folklorist with the Center for Louisiana Studies of the University of Southwestern Louisiana, Lafayette.
The book was printed in 1984, so some current performers are not discussed, but included are the best-known performers of that time and before, including:
Dennis McGee and Sady Courville (McGee was the best of the old time Cajun fiddlers)
Lula Landry, Inez Catalon and D. L. Menard
Lionel Leleux and Don Montoucet
Varise Connor
The Fontenots and Ardoins (fusion of Black Creole and Cajun)
Clifton Chenier and his Band (urban zydeco)
Zachary Richard
Nathan Abshire
Octa Clark, Hector Duhon and the Dixie Ramblers
The Balfa brotherhood
Marc Savoy (best-known maker of the Acadian Accordian)
Michaey Doucet dit Beausoleil
