I've been living in Copenhagen the past 20 years and have met many great Scandanavian folkies. Most of the ones I meet however play Irish material mainly when they are out. You might like to check out www.ashplant.dk and send a personal message to Martin O Hare. He knows just about every good player in Denmark and Sweeden and might be able to send you some good links. I'll be keeping an eye on your page. The best of luck with your project.
