Another production titled "The Gershwins' Porgy and Bess", directed by Diane Paulus, with book adapted by Suzan-Lori Parks, and music adapted by Diedre Murray, was presented by the American Repertory Theater (ART) in Cambridge, Massachusetts. The Broadway production was produced by Buddy Freitag and Barbara Freitag. Previews started August 17, and the show opened August 31, 2011. Following Trevor Nunn's latest production of the work, the ART "Porgy" was the second production initiated by the Gershwin and Heyward estates to adapt the opera for the musical theatre stage. Again spoken dialogue, here written by Parks, replaced the opera's sung recitatives. William David Brohn and Christopher Jahnke created new orchestrations for the production.
