I will never not be astounded by improvised musicals. It takes such a talented group of people to be able to pull it off, and Off Book is absolutely no exception. I am in awe of their ability to connect with each other so well that they can improvise not only scenes and an overarching storyline, but rhyming lyrics and harmonies, along with the talented pianist playing with them and the lighting designer in the booth (whole other skillsets I can't even comprehend!). The entire cast had such amazing chemistry with one another, and their comedic timing, relationships, and line and scene delivery were on point the entire time. At the end of the show I went to (where they performed "Pet Psychic: The Musical", from an audience suggestion), I walked out of the theatre humming the finale song, which was so good I felt crushed that it had been improvised and not something recorded so I could hear it again!! Would definitely recommend going to see it if you are a fan of musical theatre in any sense! I would see every show of it if I was able to, because it will always be something new and exciting.
