We all know preconceived notions can be toxic for improvisation.  But what do you do when premises are ingrained in the format you're playing?  This week Adam and Rob recount their experiences writing through improvisation at Second City, improvising through heavy offers in the Armando, and navigating premise-heavy beatprov.  A special dedication to Sebastien Fazio.  Find us online @thebacklinepod on Twitter and Facebook.
