Set in an immersive church basement, a group of 8 "Friends of Saul" gather for their weekly meeting. Their meeting is about addiction to technology, and it's brilliantly written. All 8 characters get their moment to share with the group, and do so in a "chamber choir musical" manner - no instruments, just the group and their voices. It's not necessarily acapella, but it has a similar vibe.
I have absolutely no idea how Malloy wrote 8 part harmonies for 110 minutes of near constant singing, or how the actors have memorized each melody to a T, with no conductor.
The show is broken into two parts, and the second part is some of the most thrilling theater I've experienced in a theater this year. The first part is good as well, but follows a very traditional format, that I'm sure the whole audience will appreciate they break quickly.
It's relevant without being forced, and it's engaging without being cliche. The cast is diverse and epic, with each performer really making their mark subtly on the whole evening. There's one only one scene/song I think needs work, as it features no singing and is a bit long.
Show is mostly sung-through, there are is some dialogue here and there, with one of the aforementioned character scenes being spoken, not sung. Entire cast is on stage the whole time. Truly thrilling.
