Christo's concert included the filk debut of Erin Kean of the Filk Film Project. She's the third head of the three-headed alien in the middle of the stage. (C'mon, use your imagination.) We first met these filmmakers at GaFilk in Atlanta (photo), and they seem to be very interested in capturing a true sense of what it's like to be a filker.
I'm not sure if Erin's participation is bad because it removes her journalistic detachment, or if it's good because it gives her a better perspective. Either way, the more time I spend talking to these people, the more excited I get about their project.
