Rachel Farley is kind of a bad a-- on stage. In her studded black leather jacket and blue jeans, the singer -- who toured with country bad boy Brantley Gilbert before she could legally vote -- is a commanding presence. Sure, she's only 18, but she's known more life and death than some twice her age, right? 'Ain't Easy' began with a story about her grandfather running moonshine. Her new single 'Midnight Road' hardly backs off the throttle.
