In 2007, Robert Plant & Alison Krauss released Raising Sand, one of the most acclaimed albums of the 21st Century. It was an unlikely, mesmerizing pairing of one of rock's greatest frontmen with one of country music's finest and most honored artists, produced by the legendary T Bone Burnett. Now, after 14 years, they return with Raise the Roof, 12 songs from a range of traditions and styles that extend this remarkable collaboration in new and thrilling directions.
