Whenever I hear the is it country or is it rock arguments I reflect on that country at the birth of what we of the WWII Korean War generation call Rock is where most of it started. Elvis, Conway, Jerry Lee, Wanda Jackson, Sonny James, and on and on. There is a constellation of lesser know rock-a-billy stars such as Warren Smith and Billy Lee Riley. Some might even put Buddy Holly in there and of course Waylon and Hank Jr.
Once rock turned the corner past Metal and got steamrolled by Hip Hop and Rap, many rock fans of my generation got frustrated and gravitated to country. At the same time many aging rockers saw the opportunity to gain audience by releasing country tinged recordings.
As a kid back in 1950s and 1960s Southwestern Ohio I was in the footprint of WSM's powerful nighttime signal and sure as there is snow in January my Dad and Mom had their radio tuned to 650Am on Saturday nights. The locally produced "Midwestern Hayride" was timed to not completely overlap the Opry. But as a kid I was not that fond of some of the "Hillbilly" stars like Roy Acuff and his like. I tolerated Red Foley, Ernest Tubb and others. But Sonny James, Bobby Lord got my attention. L was a fan of Patsy Cline but not so much Kitty Wells.
My point being that Country evolves and now the circle that is Country has come back around. In the end I take them one at a time and some I like such as Brad Paisley and Kellie Pickler. Others not so much like Taylor Swift. I am solid with George Strait and Toby Keith. But over time I've embraced and now collect some of the oldies and I now own some Kitty Wells and Jean Shepard David Houston and Hawkshaw Hawkins to name a few.
I am also building a library of Rock-Billy and R & B forgotten performers like Wynonie Harris. But at the same time I will listen to new stuff and accept and reject based upon merit,of course by my ears judgement. SO it is all subjective and the problem is the bean counters and statisticians trying to force feed a common and limited one size fits all format on stations across the nation. Live and local has more to offer than tracked and flown on the bird. There is no regional flavor like there used to be.
