The problem seems to be that it's not possible for anyone performing traditional material to be different from anyone else, unless they present it in a different way from their predecessors.

If they don't change anything, they are regarded as more of the same, and not different or innovative enough; whereas if they do change anything, e.g. use electric instruments, they are then accused of not being bona fide folk performers.

So it seems there is no solution to the problem.
