I'm on a new improv team called Devastation and we'll be doing longform improv (a 20-30 minute show that's all made up on the spot). This show is free!
This improv team was created through SUPERNOVA, a very cool program run by Nicholas Feitel and Amey Goerlich, which puts together improvisers who don't already know each other from all of the different theaters in the city. Cross-pollinating hilarity! Check them out here: http://supernovaimprov.tumblr.com/
