It looks like September is for shifting all kinds of perspectives.
I hung around on the improv comedy scene as audience-only for many months before I got up the nerve to take classes. At that point I had a group of friends on the indie-scene (ie, improv teams/performers/shows not part of a particular teaching theater) who convinced me that improv was fun rather than terrifying in the first place.
Early on I figured that indie-improv peeps are super busy with their indie projects, and there would be a big experience gap between them and myself, so I would find people at the Theater where I took classes to play at improv with. Maybe someday in the far off future I'd get to play with my indie friends.
Things haven't really turned out as expected. I'm about to start Level 4 at the Theater (Adept Level Improv?) but still having trouble finding things to do outside of class. Leveling up doesn't mean much if you don't have an adventuring party.
The Theater doesn't have a lot of room for n00b-shows (which totally makes sense if they want to sell tickets, basic theater ecology ;-}), so I don't really get to play there except for improv-jams and my class performances. I've almost been involved in a couple of Theater projects, but last minute rule-changes and cancellations left me out of the loop. Not many in-class contacts have led to new practice groups.
On the other hand I've had a few invitations to improvise, mostly at practice groups and one-time shows, from indie-scene friends. It's not a huge number of invites but any score vs. zero is a solid win for the independants. Despite my being absent from indie events for a long time because I was hanging around the Theater, so I'm surprised to even be invited.
The Theater is fun to hang out in and has great shows and classes, but maybe it's time to get back to the indie scene. That's where the work/play seems to be for me. I miss my indie friends and feel bad for having being away.
I am also trying to start my own practice group, because "If you want something done, do it yourself." I have a mix of people from different sides of the improv scene interested and I hope I can get it to work out :-)
