I wonder if there any conclusions to be drawn that they don't seem to be on any folk festivals these days. Last time I saw them at a folk fest, half the audience left out of boredom.

Maybe they are more exciting these days, and get the audience jumping about.

It seems they are marketing themselves away from the 'folk' label and are aiming at a more crossover audience.

Nothing wrong with that as such - makes good business sense. Let's face it - the Laura Marling/Mumfords audience is potentially much bigger.
