First making waves as a songwriter with classic tunes like “Crazy” and “Hello Walls,” Willie Nelson went on to become one of the founders of outlaw country, blowing the walls off the Nashville sound with fellow iconoclasts Johnny Cash, Waylon Jennings and Kris Kristofferson. During the ’70s, Nelson recorded a string of chart-topping, critically acclaimed albums, including Shotgun Willie and Phases and Stages, with hit originals like “On the Road Again” and “Bloody Mary Morning,” and classic interpretations of favorites like “Pancho and Lefty.” With fans spanning generations, Nelson is as strong as ever, recently releasing Band of Brothers, an album of new songs and his biggest-selling release in nearly three decades. Alison Krauss & Union Station featuring Jerry Douglas are one of the most skilled roots country bands around, with each member a true virtuoso. With 26 awards, Krauss is the most decorated female artist in Grammy history. She bridges the gap between roots music and country, rock and pop with such hits as “Buy Me a Rose,” “Whiskey Lullaby” and “Find My Way Back to My Heart.”
