The short answer is probably "no", but I'm glad you raised the question anyway, because I happen to like trad jazz, and there are similarities in the way both types of music are viewed by the general public (minority tastes, virtually ignored by the media, etc.); and a certain amount of overlap too, in the material (e.g. many trad jazz adaptations of folk songs). Yet both types of music have a relatively small but thriving fan base (AFAIK, I'm a bit out of touch with the trad jazz 'scene' these days).

I've been to a few outdoor trad jazz events in the summer and had as good a time as I've had at many a folk festival.

But I doubt trad jazz would be accepted in your average folk club, or I daresay vice versa.
