Successful modernisation becomes almost completely unnoticeable in a generation. think of the sounds of the Chieftains, Planxty and theDubliners for example, in the context of Irish folk music.A majority of listeners nowadays hearing a few seconds of any recordings would pigeonhole them as the traditional end of Irish (or "Celtic") music.Of course there was nothing"traditional" about any of those very different sounds, they were three quite separate contemporary attempts to interpret material of folk origin. They were successful. They now sound traditional to everyone except those who have a particular detailed interest in the subject.This is a fact, and has no connection with whether you like it or not, or whether you think it ought to happen or not. Folk music mutates faster than any of us can think or keep up. Great!! (Which should not be taken to mean I like every djembe/didgeridoo/bagpip/computer band I hear at Glastonbury.
