The reason for that is simple.

Write to the BBC and DEMAND more folk and roots. And then when they ignore you write again.

And tell all your friends to do it. ~And then get them to tell all their friends to do it.

There are 350 folk festival (approx) in this country and the number of jazz festivals can be counted on the fingers of one hand. Demand that the BBC reflect this.

And they will point to local radio as the place. Tell them it isn't.
