Well, on the face of it, this looks like a very imaginative enterprise.
Two comments, though: firstly, subscription. As the BFBB will no doubt testify, charging bands an unrealistically low subscription (in this case, £50 p.a.) severely restricts your activities, irrespective of good intention. £25 for individual membership, on the other hand, is more like it, and in line with subscriptions to many other organisations of all different types. Let people who want to support this idea show their commitment by putting their hand into their own pocket, not the band bank account, and provide the organisation with a realistic income which it can use to further its policies.
Secondly: the EFBB show commendable imagination, with policies including an English National Brass Band, an Ombudsman, and a health partnership to encourage asthmatics to take up brass. So it is rather surprising that nowhere in this fine venture is the commissioning of original music mentioned. Surely this is merely an oversight, caused by the inability of the EFBB to cope with the flood of ideas?!
Incidentally, I wonder if any thought has been given as to how a developing EFBB might impinge on the activities of the BFBB, and whether it might be detrimental? Just a thought.
