In the American South, traditions from Celtic music, folk, blues, gospel and mountain music melded together into what was originally known as Hillbilly music. Hillbilly produced some incredibly popular artists like Jimmie Rodgers, who sold over a million records in the '20s, back when there were probably like 2 million people in the country.
In 1949, Billboard started referring to it as Country, since many Hillbillies began to feel like they were performing some kind of minstrelsy for urban, northern audiences who'd stick some straw baies on the stage to make these noble savages feel at home.
Anyway, it wasn't just popular at home. There are seemingly more fans of country outside of the U.S. than in it. Before long, other countries were producing their own Country, influenced by the original but occasionally tailored to their own traditions.
It shouldn't really come as a surprise that Canada, our kid sibling to the north, would have their fair share of Country musicians. in fact, outside of the U.S., Canada is the Countryest country. Originally it developed out of their heavily Celtic Maritime Provinces. Most Country, however, mirrors the U.S.'s and many Canadian Country artists have infiltrated Nashville unsuspected and undetected, capable of producing Pop Country as bland as our indigenous experts. Most Canadian Country musicians sing about Tennessee this and Kentucky that, happy to not reflect their own backgrounds. Those that do have a more distinctly Canadian tone often have an elevated Folk aspect to their music.
Canadian Country artists include Shania Twain, Adam Gregory, Hank Snow, Paul Brandy, Wilf Carter, Tommy Hunter, Stompin' Tom Connors, Corb Lund, George Canyon, Don Messer, Anne Murray, Lucille Starr, Marg Osburne, Ian Tyson, Mercey Brothers, Maurice Boyler, Gordie Tapp, Carroll Baker, Bob Nolan, Stu Davis, Gene MacLellan, Myrna Lorrie, Ray Griff, Ronnie Prophet, Colleen Peterson, The Good Brothers, Terry Carisse and Prairie Oyster.
