As one who spends a lot of time examining the finer details of medieval churches, I also appreciate them in terms of their acoustics - especially if undampened by carpets! Check out my adventures as SUNDOG for field-recordings I've made in various churches and there's a Black Sea Fiddle improv HERE (track 4) recorded in in St. Swithin, Launcels last year which is as much church as it is fiddle.

Also this, from St. Margarets, Cley-next-the-Sea back in July. Shite sound, but you get the idea...
