The vinyl resurgence is due to YOUNG folks getting into vinyl. I think the young 'Country' types just would rather spend their money on extra beer and bullets.. rather than on vinyl.
That is my experience with them anyway...
The records being pressed are new Rock, Old Rock, and old jazz...
Not Opera, not Classical, and not Country.
The market is just not big enough to bother.
Country folks are always a bit 'behind the times' anyway, so give it five more years, and if the vinyl resurgence is still happening, you might see a few new country vinyl issues.
(and I agree Country HAS become pop with a cowboy hat..)
