"from the English Acoustic Collective."

Indeed!

And whose web pages include this:-

The EAC continues its holistic approach to traditional music making at Ruskin Mill, Nailsworth, Gloucestershire. 17 places are available for a week designed to engage fiddle players from all backgrounds and levels in the development of their own style. This year we will also open the course to non-fiddlers who are keen to develop their personal style.

Now what do we think Holistic means?

Clue they tell us in the phrase "all backgrounds and levels"

Diane, some of us are rather more informed/widely read than you give us credit for.
