Earle released "Copperhead Road" on Uni Records in 1988 which was characterized as "a quixotic project that mixed a lyrical folk tradition with hard rock and eclectic Irish influences such as The Pogues, who guested on the record". The album's title track portrays a Vietnam veteran who uses his family background in running moonshine to become a marijuana grower/seller. It was Earle's highest-peaking song to date in the United States and has sold 1.1 million digital copies there as of September 2017. Then Earle began "three years in a mysterious vaporization" according to the "Chicago Sun-Times".
