No other genre of music has a festival during which fans are any closer to the artists than at CMA Music Fest. And at the event's AT&T U-Verse Fan Fair X experience, country superstars got up close, personal and really candid with their fans. Artists of the Day at the CMA Close-Up stage included Hunter Hayes, Little Big Town, Darius Rucker and Chris Young, with all four performing and taking questions (nothing off-limits) from the audience. There were also songwriters' rounds, charity auctions and celebrity panel discussions on the large stage inside Nashville's Music City Center. And outside, anyone could be a star on the AT&T Country Deep Live Karaoke stage. Flip through Rolling Stone Country's best photos of Hayes, Little Big Town and a sea of fans at Fan Fair X.
