The New York Times featured East Nashville on Sunday (apparently, in the Style magazine for print customers and in the Travel magazine online):
Nashville’s Band of Outsiders - New York Times
The focus is on how Nashville is one of the few affordable, cool music scenes left and East Nashville is where many musicians are ending up.
It describes the people who are flying under the radar making music more like traditional country music (such as Patsy Cline, Johnny Cash, etc.). Such music is apparently called Americana now. It also mentions places that you can go to see them in different parts of Nashville (not just East).
I don't tend to be that interested in articles about music, but this one held my attention (probably because I much prefer traditional country music to the stuff masquerading as such now).
