Watch Sara Bareilles, Jason Mraz Record Theatrical New Duets

Pair team up for Bareilles' album of songs from 'Waitress' musical

Sara Bareilles' Web series "Making the Record" is a fun look into the singer-songwriter's recording process for her upcoming fourth album, What's Inside: Songs From Waitress, which contains music she wrote for the 2016 Broadway musical Waitress, based on the 2007 film of the same name. In Episode 4, Bareilles is joined by Jason Mraz, who records as character Dr. Jim Pomatter for the album.

In the clip, the pair show off their musical chemistry and friendship as they record the pair of songs that will appear on What's Inside. "For those who know Sara, she is sharp, quick witted, hilarious, and intelligent," Mraz tells Rolling Stone. "While this is a concept album of sorts, it still manages to showcase who she is and what she is capable of. [The album] is the work of a true artist and is sure to become a classic."

In late October, the pair debuted their collaboration, "Bad Idea." In the playful duet, the characters of Jenna and Dr. Pomatter list all the reasons why they can't fall for one another.

"I have been inspired by the work of Jason Mraz on and off the stage for years now," Bareilles tells Rolling Stone of her duet partner. I have only ever seen him make his art from a place of deepest sincerity and that is a beautiful thing to behold. He was a welcomed and gracious guest on my record and I am so thankful that I got a chance to make music with this inspired and wildly talented soul."

What's Inside: Songs From Waitress will be released on November 6th and the musical is set to debut on Broadway in April of next year.
