This album introduced the world-at-large to a new kind of country queen. Emmylou had already earned progressive-country cred as Gram Parsons’ duet partner, but her first real solo flight proved that she had a feel for classic country too. Her otherworldly quaver is just as goose bump-inducing when she’s redefining tunes such as “Sweet Dreams” and Hank Williams’ “Jambalaya” as it is on her versions of Parsons’ ominous “Sin City” and Rodney Crowell’s heartbreaking ballad “Till I Gain Control Again.”
