A lot has changed in the worlds of pop and country since Shania Twain last released an album (2002's Up!) and last went out on tour. In that time, she's witnessed the rise of crossover stars such as Taylor Swift and Carrie Underwood, as well as the chart-topping reigns of Miley Cyrus and Rihanna. Although she hasn?t been resting on her laurels, thanks to a two-year residency at Caesar's Palace in Las Vegas, it's a wonder Twain waited until now to step back onstage and remind the rest of the world what she's capable of. Rock This Country is billed as Twain's farewell tour, but as she told Rolling Stone Country recently, she feels like she has "so many other things to do musically."She also acknowledged that she's not closing the door on touring completely.??
