Meanwhile real folk music was going on in valleys and hollers up in the Ozarks and Appalachians. Occasionally a collector would pass through and steal some, and occasionally somebody would make it to the low lands and take some out with them (Carter family most famously). But this didn't even rise to the level of "blue collar" -- which presupposes industrialism. Black collar, more like, for the coal mining.

O..O
