For 25 years, Elevator Repair Service has been a leader in innovative and experimental theater in New York. ERS is currently in the early stages of planning for a co-production with the Public Theater of Shakespeare’s “Measure for Measure,” one of the Bard’s so-called “problem plays.” The ensemble offers a preview excerpt from the production, and the company and its artistic director, John Collins, then appear in conversation about the project. 92nd Street Y, 1395 Lexington Ave., Kaufmann Concert Hall. Jul. 14, 8 p.m. Tickets are $32, $15 for those 35 and younger at 92y.org.
