Carrie Underwood and Luke Bryan are set to headline the inaugural iHeartRadio Music Festival in Austin, Texas. The popular iHeartRadio concert has gathered the hottest pop music artists in Las Vegas over the past few years, and now the stars of country are getting their own festival. Concert promoters have announced the very first iHeartRadio Country Festival, which will be held on 29 March (14) in the Lone Star State's capital city. Underwood, who played at the very first iHeartRadio festival in 2011, along with Kenny Chesney and Rascal Flatts, shares her excitement for the upcoming event in a statement that reads: "It's going to be a big party for all of us. I've been lucky enough in my life to go to lots of different other genre concerts as a fan, and I think I would rather be in a country crowd than any other crowd, just because they're fun, they're singing along, they're dancing, everybody's cool to one another." Also taking the stage with Underwood and Bryan are Florida Georgia Line, Jason Aldean, Eric Church, Lady Antebellum, Jake Owen, and Hunter Hayes.
