Sorry, but that's absolute bollocks.
Look at Boka Halat. Who, you ask? Exactly. A fantastic fusion of English and African music that appeals to people outside the narrow ghetto of 'folk'. It's the sort of thinking that crosses borders rather than erects barriers (as some on here would seem to want to do).
And if that sort of music finds itself confined to BBC 2 programmes - well, good for them, because it's rather more than the average folk club offering manages to do. I'm sorry, but the 'traditional' as opposed to the 'tradarts' stuff can't seem to find airtime anywhere. Sad, maybe, but true.
So instead of sitting on a rather frail ivory tower and casting aspersions, can I suggest that those who would criticise would actually listen to some of the stuff they decry, and look at the sort of people who are drawn to it, and then sit back and think very hard. Think how they can engage the same sort of audience, and how then can make their material as fun, relevant and engaging.
Which leads us, in a commodious vicus of circulation, back to the thread about folk clubs dying....
