Here's a challenge for you, Dick.
Define jazz, classical, pop, rock, hip-hop, folk-rock, disco, etc.

They all have certain characteristics that would be recognised easily but try to see them as a Venn diagram all overlapping in some way. Why do you clamour for a cast iron definition?

I think what you quote is a perfectly good desription of what they are trying to do. You are fully entitled to not like what they are doing. Just like Vic I think that they sometimes appear to be moving too far away from the main task, but to get the funding to keep the movement going and provide all that wonderful material in the archive they have to tick a multitude of boxes and it just so happens that providing new music and opportunities for young people ticks a lot of these boxes. They are widening the net if you like, and are being pretty successful with it. Your own personal preferences and those of a few dinosaurs living here matter diddly squat in the overall scheme of things!
