Hi
To answer the thread question:
Do young Folk Musicians need new ideas? I think the simple answer is NO. There is nothing wrong with playing what has gone before. I do think though that to add your input in and bring the music to the present is far more risky, as once you change the straight 'tradional music' and change it into something different you run the risk of not being 'traditional' etc.... and of people basicly not likeing it.
People don't like change, although I quite like it in music as it is exciting.
Cheers, Sam
