I agree Tom. There have actually been conferences using the words "folk music industry"
Prepare for the sky to fall on you.
Those not involved in it would be appalled at the riders some of their well loved bohemian "we're not in it for the money" folk singers have on their contracts with their employers. A well known, nay, legendary British singer who has worked all his life in the folk world has enforcers who bully backstage while he chills out in his dressing room. Others demand crates of ale, specific wines, certain foods, state their hotel must have a certain number of stars,
etc, etc. They are no different to the ego ridden celebs of showbiz, except that they profess to not belong to that world. It's all status driven, and definitely at that level, an industry a world away from the sing around.
Believe me, the big festivals are a hot bed of clashing egos and status driven judgements. Don't go there, stay out front and maintain your illusions!
