Off Book: The Improvised Musical

Off Book: The Improvised Musical is a musical theatre podcast hosted by Jessica McKenna and Zach Reino. The show improvises a new musical every episode based on their guests' introduction. The show headlined at the 6th annual SteelStacks Improv Comedy Festival.

Background
Zach Reino and Jessica McKenna met in 2011 at the Upright Citizens Brigade Theatre in Los Angeles, California and went on to create Off Book: The Improvised Musical. During each show, McKenna, Reino, and a guest improvise an entire narrative musical while Scott Passarella plays the piano. Each week the musical is started out by their guest, and the rest of the show is based on the guest's introduction. Sometimes the guests do not have a background or experience with singing. The podcast was produced by Earwolf, but in 2021 the show moved to Art19 Media.
