From Austin Improv Wiki
John Buseman is an improv performer.
John Buseman started improvising in 2008 at the Philly Improv Theater. He moved to Austin in November of 2009. Currently, he mostly focuses on stand-up comedy instead of improv.A post from him about the first improv show he ever saw:
UCB tour co came to my college. For someone who didn't really know what improv could be, and only knew UCB from their comedy central show it was mind blowing. Bobby Moynihan played. I knew him from that derrick video. Then I forgot all about improv until I graduated and found there were groups in Philly.
