I'd commission someone like Will Hodgkinson, author of Ballad of Britain, to travel round the UK with maybe just camera and sound persons, doing 'field recordings' of some of the myriad of superb but lesser-known singer/songwriters who are creating the new local folk music. It should be recorded at folk clubs, local concerts or in people's homes, so nothing overproduced - just 'warts and all' recordings in the spirit of Cecil Sharp and the other early collectors.
