wasn't there a feature in one of the broadsheets recently about that phenomenon in Manchester? It seemed to be centred around one club, but justified by the fact that they were planning to open similar clubs in other cities...

I doubt it's a "folk" that many people here would recognise - but that's because folk and acoustic have become interchangeable terms in the media and recording industry.

But this is also an example of what a broad spectrum of young people is represented by the word folk. And another exmple of why the word has lost any intrinsic meaning, TBH. Maybe we should just give the F word to them, and find another word for the stuff we do...
