Hi again, Folkfan!
"Folk" is an interesting idea. There's an article from 1993's New York Times on the "death" of American folk music in the 1960's (
http://query.nytimes.com/gst/fullpage.html?res=9F0CE2DD1730F933A05756C0A965958260). The article basically says that there is little or no "real" American folk music, in the sense of traditional unwritten songs (I guess Native American music didn't count?), but the folk boom of the 40's-60's (Woody Guthrie et al.) was actually an attempt to create a "folk" music for America from scratch.
But folk doesn't seem to know that it's dead. It's got musicians and fans, and they all sort of agree on what they are about. I guess you could call it a community that looks back to Woody and company to one extent or another and sometimes plays acoustic instruments. And if you play at Falcon Ridge, I guess you are in that community, so Vienna is. All of the artists we are talking about are "popular" folkies (get played a bit on "adult" rock stations), but, just my own opinion, some like the Nields and the Kennedys seem to look back to the roots a little more than others. (You can find real diehards elsewhere, such as WUMB from Boston, or radio.grassyhill.org. Dar and the Nields are at the "pop" extreme of their playlist.)
Speaking of radio airplay, I find Vienna's lack of airtime on NYC radio distressing. I'd have never found her without the internet. "City Folk" WFUV (which is really more of an adult soft rock station than anything else) would be most likely to play her, but I found exactly 1 play in their playlist archive, years back. Does/did she get more play in the Bay Area, does anyone know?
Oh, and Cry, Cry, Cry? Loved 'em, especially the acoustic guitars and 3-part harmonies on REM's Fall on Me. However, I've never been tuned into the gossip enough to know why, since then, Richard Shindell and Lucy Kaplansky perform together seemingly every time they are on the same continent, but Dar has never, that I know of, performed with either of them since. There is an obvious answer, but I have no idea if it is even close to the truth.
Take care,
Fred
