Oh the pompousness, oh the pretenstiousness, poor tempores and mores.
Are you seriously suggesting that you know more about folk music because you have read some general music encyclopedias, watched some beeb and listened to 'Voices' that you know more than someone who has been part of the scene for years and works at THE largest center in Britain for the study and promotion of folk music?

Here's a question, does imperialism for you mean imposing one's culture and set of ideas on someone else?
