Atlanta was the first city to have country music. WSB (Welcome South Brother).

It was the scene of the first major fiddle contest held at what is now
Georgia State University. "Fiddlin" John Carson would win most years.
I recommend a book "Pickin'On Peachtree" by Wayne Daniels.

Lowe Stokes won sometimes and was the subject of the poet
Vachel Lindsay in his "Mountain Whiporwill"

Eck Robertson was a well-known Texas fiddler.

Bobby Hicks, Johnny Gimble, and Johnny Frigo (Chicago Barn Dance).

All kinda' Texas (Southwestern swing style) players.
And Mark O'Connor.
