The Second Beat is a tiny little gem of a black box theater in Phoenix. Classes available too for folks who want to learn some long form improv. I have been in the audience, in the classes and even in some shows. This place is about being playful and having fun. I wish I could knock out the back wall and add seats so more folks could enjoy the shows. I always go online and book seats because sometimes they sell out quick.
The Skewed News show on Friday nights at 7pm is consistently well done.
