The duet can be found on Larsen's debut solo album, "Sing You To Sleep," which was released in December 2014. Mueller, who nabbed a Tony Award for her performance as Carole King in the hit musical, will also be on hand to perform at Larsen's March 23 concert at New York's Birdland in celebration of the album's release.
Larsen, also a Tony nominee for her portrayal of Cynthia Weil in "Beautiful," told The Huffington Post in an interview that her new album was, in many respects, the culmination of "an extraordinary whirlwind of a year."
"A year and a half ago, I was really at the lowest place in my life," she said. "On all the major fronts in my life -- professionally, romantically -- it felt like nothing was going right. I felt like I needed to quit the business, because it just felt like it was masochistic and ridiculous."
Just days later, Larsen's agent called to tell her that she'd landed the role in "Beautiful," which turned out to be a smash hit. It was through her dresser on the show that she was introduced to musician Freddie Maxwell, who appears on "Sing You To Sleep." The couple, who are now expecting their first child, married earlier this year.
Although the 12-song collection has been billed as a collection of lullabies, Larsen hopes adults will find "Sing You To Sleep" just as enjoyable as their kids.
"I wanted it to be more Norah Jones than The Wiggles," she said. "I really feel strongly that we don't need to dumb things down for children. My kid is going to be listening to Stevie Wonder."
Anika Larsen and special guests Jessie Mueller and Jarrod Spector will perform at New York's Birdland on March 23. Head here for more information.
