Real Country, hmmm.

A lot of good selections have been suggested.

If you listen to Country music across the decades, starting with the Carter Family and Jimmie Rodgers, you will find two concurrend streams:
1. Country music that reflects the pop music trend of its time and
2. Music that has more the feel of "it could have been in a living room on a farm". (Even if it is amplified.)

ad 1:
1930s: Bob Wills, Spade Cooley and all the other Western Swing bands played Jazz;
1940s: The Delmore Brothers, Arthur Smith and others played Boogie Woogie style music.
1950s: Even Eddy Arnold recorded Rockabilly songs, Country music's adaption of Rock 'n' Roll. And there were others like George "Thumper" Jones, Hank Snow, Johnny Cash and many, many more.
1960s: Sound carpets by very large string orchestras enhanced Country music to have it have an easier access to the pop charts.
and so on...
the reason to invent outlaw country music, you know Jennings, Nelson, and their friends.

ad 2.
All the music that is seen as "real" country music including all the other sub-genres like bluegrass or gospel music for instance.
