Hi Silas - I'd wholeheartedly endorse your views on dumbing down - let the music be what it is.

As far as filming a live concert is concerned, of course there are different constraints from doing a documentary. But, as other BBC folk music concert programmes have proved, it's possible to do a first-class job. I keep quoting the Springsteen Seeger Sessions Band concert as an exemplar. It wasn't a complex programme visually, but the sound quality and mixing was superb. I suspect that the post-production sound of the Christmas Sessions left a bit to be desired - possibly rushed. But who knows...
