Dear all, I've been missing for a while, so I don't know if this topic has been mentioned before. Anyway, I just finished a fine academic book published by Oxford Unifersity Press, "Electric Folk" by german scholar Britta Sweers (
http://www.oup.co.uk/isbn/0-19-517478-X). It's about changing attitudes in british tradizional music and focus on electric (and sometimes jazzy) folk. FC work is obviously often discussed. One chapter is dedicated to a biographical survey of main performers, and it is the less interesting for hard core long time fans, as most of us are likely to be; when the author write as musicologist the discussion goes deep into a passionate analysis of styles and approaches -especially recommended the one about Sandy Denny.
