There is a very good essay in the October issue of Sojourners titled "Cultural Channeling." It begins by talking about the passing of Agnes Cunningham, but goes on to say some interesting and insightful things about the music it calls "old-time country music" and authenticity in music.
The piece concludes with these sentences;
"Or is it really the sound of something human and real struggling to emerge from the virtual? Maybe old music -- and perhaps old religion -- is all we have left from which to concoct a new way of life."
Yes!
And there is a picture of the Alamanac Singers.
