Best known as one half (with Kristian Bush) of GRAMMY-winning country duo Sugarland, Nettles announced last year that she was recording her first-ever solo album�and doing so with producer Rick Rubin, who's worked with a wide range of artists, from the Beastie Boys and Slayer to the Dixie Chicks, the Avett Brothers and Johnny Cash. "I'm super-respectful of his pedigree," Nettles has said of Rubin. "I still get nervous around him, in a kind of a music-crush way."

Nettles called her new solo album "a celebration of my roots, and where I am today." She previewed the material during special acoustic shows in select markets, which gave fans a taste of what to expect. And she released one song, the title track, to country radio, where it's been steadily climbing the charts over the last few months. "I wrote ['That Girl'] with Butch Walker, he brought the idea over," Nettles explained to Radio.com.

The basic idea of the song, she continued, is of a woman "who had been tricked, bamboozled if you will" by a man she had been seeing, who didn't let on that "he had someone else in the picture. But when she finds that out, she says, 'Oh no, I'm gonna call her and tell her that you're being that guy, because I don't want to be that girl with that stigma.'"
