Fringe festivals offer so many plays, how do you sort out the best and makes sure people get to see them? The New York Frings has an idea: “Ten of the audiences’ and critics’ favorites from the current festival will run in repertory at two downtown theaters through Sept. 24 in what the organizers, Britt Lafield and John Pinckard, say will become an annual showcase called FringeNYC Encores. For the Fringe, this provides another opportunity for its shows to be noticed by producers and earn a possible commercial transfer.”
