The latest New Yorker (28/04/08): "This week in the magazine, Burkhard Bilger writes about the folklorists Art Rosenbaum and Lance Ledbetter and about field recordings of folk music."

The article itself does not seem to be on-line, but there is an audio interview with the author available - I haven't listened to it and I don't know if I'll be able to because of my lame connection, so I can't make any judgement on its content, other than that I suppose some of you might find it of interest.

There's also a link to a "slideshow" on that page; seven photos of some of the subjects of the field recording in Georgia, US.
