Popular female country artists like Kacey Musgraves and Maren Morris have scored major pop crossover hits, made huge splashes in the vinyl market and perform for sold-out crowds across the United States, yet barely have a blip on country radio. Though far from a new phenomenon, it's one that has drawn battle lines over the last two decades between gatekeepers of a genre dominated by white males and a rightfully fervent opposition seeking accountability, diversity and equal representation. On this week's episode, music journalist Marissa R. Moss (Rolling Stone, Billboard) explains how she tackles these issues and more in her new book, "Her Country: How the Women of Country Music Became the Success They Were Never Supposed to Be" (available today, May 10th). We also dive into why Sturgill Simpson's latest record is best enjoyed on vinyl, the rise of Nashville's Black Opry, and how life events influence how we hear and appreciate music.
