Carrie Underwood has always taken time out of her busy schedule to participate in CMA Music Festival, which takes place this week in downtown Nashville. She tells us why the event is a one-of-a-kind. “The greatest thing about CMA Music Fest — the whole week — no other genre of music does this, you know? This is so unique to country music. It's so unique to Nashville. People come from all around to come here and just have fun for the week, and it is something that, you know, this kind of fan appreciation just doesn't happen anywhere else.” . The show also features performances by Blake Shelton, Old Dominion, Luke Combs, Brett Young and Charley Pride.
