"The Makers of Cajun Music- Musiciens cadiens et créoles" is devoted to the musicians current at the time of publication, 1984. It has some historical data, but that is not its main focus.
Helpful is a note on Cajun terminology.
The first recording of Jolie Blonde by the Breaux was called Ma blonde est partie. April 19, 1929. The lyrics actually were written by Améé's sister, Cléoma (Cléopha), according to her daughter.
The Discography in the book is based on collections that were available in 1984.
A good list, seems comprehensive, of the Louisiana and SE Texas Cajun musicians is in Wikipedia, "List of People Related to Cajun Music."
