I attended the second-to-last preview of Octet before its West Coast premiere on Wednesday.
It's a cleverly constructed show, and the audience can enter onto the stage to check out what seems to be a self-help group for social media addicts before the musical starts. There are inexpensive tables and chairs, with the cast members drifting in one by one and sitting down. (The furniture is later used for percussion.)
I'm a fan on Dave Malloy, and some of the songs reminded me of the music he has written for other shows. The musical gets off to a strong start, and is often quite funny - albeit in a twisted and melancholy way, as the characters, one by one, describe their addictions - interspersed with group numbers led by Paula (though the regulars know the drill). They are best described as monologues set to music.
Octet gets off to such an impressive start that I found myself disappointed when it veers off into even more adventurous territory in its second half. It's not that it's impossible to follow, though the monologues get more extended and self-consciously intellectual. The second half may be more of an acquired taste, but my reaction was that the musical lost some of the tight structure and sly commentary that worked so well in the first half.
The actors, all but one of whom was in the Signature Theatre production in 2019, do an impressive job and the "chamber choir" format wasn't a problem for me. There is a lot of imagination put into the staging of each song, and I found myself - sitting on the far right in the second row - realizing I wasn't able to always catch it all. (Kitsune is correct that sometimes the performers' backs are to you, but unless I sat further away, I don't know how that could be fixed. The bright side about being close is that you're really close - and Peet's Theatre (which holds a maximum of 401 people) is very intimate.)
I didn't agree with some of the commenters on the original thread for the show who thought Malloy was lecturing the audience about the stupid people who do dumb stuff on the internet. His goals seem far less simplistic, and the characters, by and large, are portrayed sympathetically even when they're a little crazy. My primary problem, as someone who tried to go in pretty cold, is that I felt like Malloy got a little self-indulgent, requiring the audience member to do some research afterward to grasp all of the ideas he was throwing out.
