I have a tape somewhere of Joseph Cormier, a fiddler from Cape Breton. Foot percussion was very much a characteristic of his playing and fortunately the record producers didn't feel it necessary to exclude this aspect of his performance from the recording. It adds a great lift to the sound, as is the case with the above-mentioned La Bottine Souriante, and other performers from Quebec and the Maritime Provinces. To some people, it's just an essential part of the whole performance. Of course it's possible for a listener to focus on something they find annoying, to the detriment of their personal experience - but that's what it is, a personal distaste - I doubt if anyone else noticed.
