Emmylou Harris practically invented Americana in the ‘70s with her gentle blend of folk, country, pop, and rock 'n' roll. Generations of rootsy crooners are forever indebted to her—Kacey Musgraves' mix of old-school country with a modern mindset, Gillian Welch's keening folk balladry, and Neko Case's headstrong, introspective story-songs are only a few of the countless examples of Emmylou's lasting influence.
