As far as I can tell, here's the dealio for Nashville - at least, from a geographic perspective of where the various members of the music industry reside:
Big-name $ stars, producers, CEOs, etc: Somewhere out of town in a gated or secluded estate setting.
Serious songwriters & musicians: East Nashville.
Not there yet (i.e., in demand) or wanna be songwriters & musicians: West Nashville.
I'm currently sitting in a wi-fi friendly east Nashville coffee shop, noticing the blend of artsy/bohemian, urban, white collar types rolling in. I'm told east Nashville was pioneered by the gay community first, who also gentrified it and injected some culture into both the residential and business aspects. Case in point: Tim Beattie & I popped into some small, unremarkable-looking liquor store last night and was blown away by the wine selection & prices. Obviously, someone there knows wine and there's the clientele coming through there to buy it.
Foix gras and writers in the round, anyone?
