The deep entrenched divisions that are expressed here, amongst those who probably love lots of the same folk music, just encourages the myth that there is an "either or" choice between experimentation and traditional conventions in delivery

Its not either or
Only yesterday I had the lovely surprise of hearing 3 random songs in the car:
May Bradley: Under the Leaves
1st track of Bellowhead 1st album
then a track off a CD od West Gallery music that I have

it was all great to me

I didn't for one minute think that I had to choose
I know many might say they are just expressing what they like and they have the right to do that - but the repeated vehemence of these arguments suggests a deeper difference, and does, in fact, push people much closer to an either/or approach. It certainly does me and I don't like it.
