I listened to and learned from the album “Traditional Cajun Fiddle: Instruction” which I found on on Smithsonian Folkways. The album was recorded in 1975 by Dewey Balfa and Tracy Schwarz to teach fiddle technique and classic tunes such as “J’étais bal au hier soir.” Attached below is my own rendition.
