The good-time harmonies of this Nashville-based trio have become a favorite of country music fans, who have consistently rated Rascal Flatts -- Joe Don Rooney and cousins Gary LeVox and Jay DeMarcus -- among the genre's top acts. Their No. 1 hits on Billboard's country charts span a decade, from 2002's "These Days" to 2012's "Banjo." The group will take to the stage at Columbia's Merriweather Post Pavilion at 5:30 p.m. Sept. 2, with opening acts Little Big Town and Kristen Kelly. Tickets are $45-$75.
