Pop superstar Kelly Clarkson used her titanic voice for a stirring performance on "The Today Show" on Monday (Dec. 5). Taking on "It's Quiet Uptown," which she recorded for the new Hamilton Mix Tape, she soldiered through the song's harrowing story to deliver a knockout moment. "The problem is, you want to be emotional," she said just before the performance to show hosts Matt Lauer and Hoda Kobt. "Legit, no sound will come out of my mouth if I start crying."

Clarkson also shared the story of how she got involved with the project. "It was actually my new label [Atlantic Records]. [Chairman and Chief Executive Officer] Craig Kallman called--actually, I was emailed the song at like one in the morning and I was pregnant with my little boy [Remy]," she recollects. "And I had not seen 'Hamilton.' Really, I'm just a couple weeks away from having my boy, and this song is about a boy dying. I was like 'are you serious right now? I'm so worried about a miscarriage.' But it was so beautiful."

Clarkson also performed "White Christmas."

The Hamilton Mixtape (out now) also features contributions from Usher ("Wait for It"), Nas ("Wrote My Way Out"), Alicia Keys ("That Would Be Enough"), and Sia, Queen Latifah and Miguel ("Satisfied"), among others.

Next Friday (Dec. 16), Clarkson hosts her Miracle on Broadway fundraiser. The lineup includes Reba, Kelsea Ballerini, Steve Wariner, "Nashville" star Charles Esten, Ronnie Dunn, The Steeldrivers and RaeLynn. “I love my adopted hometown of Nashville with all of my heart and I am so honored to be able to give back to the community alongside some of my favorite artists and friends for my first annual Miracle on Broadway benefit concert!” Clarkson previously said of the event. “I thank all of the artists joining me, as well as the people of Nashville for making me feel so welcome over the last 7 years I have called it home!"

Earlier this year, the original "American Idol" signed a new deal with Atlantic Records. She is currently working on her new album, tentatively expected to drop next summer. “[The album is] very much my personality,” she previously said. “I think it’s very much what people expected from me off of watching me on Idol. I sang all these Aretha [Franklin] things, I love Tina [Turner], I love Mariah [Carey], I love Whitney [Houston]. I think it’s very much what people expected in the first place. I love all my stuff that I’ve done but this is the record that has been in me since junior high. And that music from when I was in junior high is now coming back [into style] — like our 15-year-old listens to R&B that I listened to in high school.”

The album's first single is set for an April release.
