"Walkin' After Midnight," "I Fall To Pieces," "Crazy" — these songs helped define not just country music, but American popular music in the post-war era. Patsy Cline's tremulous contralto helped make those songs indelible. It also helped her reach equal footing with her male compatriots. Cline died in 1963, before she had a chance to complete her fourth album — which was slated to be her full-on crossover from country. But artists ranging from Loretta Lynn to Marc Ribot have shown that even her most down-home records influenced the wider world of music. "I remember my dad telling me to listen to the way she told a story," said LeAnn Rimes. "I remember feeling more emotion when she sang than anyone else I had ever heard."
