Demi Lovato's new music from her upcoming album Confident has thus far been sassy and bold with the release of "Cool for the Summer" and "Confident," but that doesn't mean the album doesn't have its serious moments. And on Tuesday night (Sept. 29), the 23-year-old pop star proved that by debuting "Stone Cold" live in its entirity a concert at the Highline Ballroom in New York City.

Lovato was on hand to perform during an advertising week event and for what seemed like a mildly indifferent audience, she decided to play to her strengths by belting out the big, bold ballad.

"Stone Cold" starts off small and quiet, with the plucking of a deep, hearty standup bass while Lovato whispers and croons. But, as the song goes on and grows, Lovato crescendos into her always strong head voice and blasts off into space. Meanwhile, the music underneath her stays simple in an arrangement of strings, and it's enough to give you chills.

Lyrically, "Stone Cold" tackles feeling emotionally numb after a startling break up. "Stone cold, baby / God knows I tried to feel / Happy for you / Know that I am redefined / And I understand, I'll take the pain / Give me the truth, me and my heart / We'll make it through / If happy is her, then I'm happy for you," she sings with noted heightened emotion in her voice.

If this song doesn't get her the Grammy nomination, well, few things will.

Lovato's new album Confident, which features the track "Stone Cold," will be released on Oct. 16.
