Dwight Yoakam released “Guitars, Cadillacs, Etc., Etc.” in 1986, bringing a rock and roll swagger and hard-hitting style back to country music. At a time when Nashville record labels were embarrassed by the term “hillbilly” music, Yoakam embraced it. He said he was proud of his hillbilly roots and the music’s legacy. The album would sell two million copies.
