Kendra's Flying Lauders

 is a gymnastics troupe that travels to venues such as the Dreamscape Theater in Jrusar. As NPCs, all members of the Lauders are played by Matthew Mercer.

Description
The Lauders are a family-operated troupe of singing acrobats, led by Kendra, the matriarch. When they perform, their gymnastics routine is extravagant and involves props. They are accompanied by their own rhythmic chanting, which then becomes a harmony accompanied by musicians as the show progresses. Patrons who attend their performances based on word of mouth are sometimes disappointed that they aren't flying otters.

In the middle of the performance, an acrobat missed the trapeze and fell onto the stage from a great height, prompting an early yet not entirely abrupt end. The soon-to-be-named Bells Hells went backstage and saw the troupe gathered around this person, doing what they could to assist with a fractured tailbone. Fresh Cut Grass convinced the troupe, and the head of the theater, Stuvan Idrio, to let them use their healing abilities. Their success helped persuade Stuvan into allowing the party to search for the source of the various recent disappearances connected with the theater.

On their date with Pretty the ogre, Laudna, Fearne, Imogen, and Fresh Cut Grass attended a performance at the theater, where the Lauders performed a successful and uninterrupted run of their show.

Quotations

 * Pretty: I tend to be more of a purveyor of narrative stage theater, but I can appreciate the interpretive dance and acrobatic aspects of the Lauders. Not my favorite, but...

Trivia
Fairly informed speculation: the rhythmic chanting in the beginning would likely be accurate to real life, as acrobats require as much deep inhaling as they do exhaling, creating quick and regular intervals. They'd likely louden as they continue their act because their breaths deepen naturally to provide their bodies with more oxygen. The swelling, worship-adjacent angelic chorus sound later on seems unfeasible with their strenuous routine, but can otherwise be attested to highly trained and tuned breath control, cathedral-level reverb (also associated with the swelling worship sound in addition to smoothing over gaps), many voices singing the same lines together (thus limiting the harmonic range of the chords associated with a climax of angelic sound, though it does compensate with volume), or a mix of the three.
