T.J. and David are internationally known, award-winning, master improvisers from Chicago's legendary scene. This in-depth look at the techniques, principles, theory and ideas behind what they do is both authoritative and entertaining. Since their early years playing the iO (formerly Improv Olympic) and the Second City mainstage theater (where David won a Joseph Jefferson award for best actor in a revue), TJ and Dave have been performing for over fifty years combined - fifteen as a team. David worked with improvisation guru Del Close, in development of the The Harold, the preeminent longform theatrical structure, and both are multi-award winning actors.

Steven Colbert says, "One of these guys is the best improviser in the world. And the other one is better."
