While watching a film about Marc and Ann Savoy (Savoy-Doucet Band), I was wondering why Cajun music, especially the fiddle style, is so raw, almost primitive-sounding.
Presumably the music has roots in French and/or French-Canadian dance music, but (judging from what I've heard) those styles are much more sophisticated, both melodically and harmonically. It almost seems as if the music has regressed on its journey south.
