ambient field recordings?
or field recordings of the Lomax style?


Either one would be interesting. Not sure anyone has tried the previous; a few sample-based artists have gone the latter route, but I don't know that I've hear much that sounds successful (as imcvspl & I have discussed at times).

Here's one that comes kinda close though: http://www.youtube.com/watch?v=NPuEHDWGQwY
