Come for an advance screening of footage from the upcoming documentary “On the banks of the tigris: the hidden story of Iraqi music,” an extraordinary celebration of music and the cultural ties that unite people across religious boundaries. When writer and actor Majid Shokor escaped from Iraq he discovered a hidden history—that many songs all Iraqis love to sing were written and performed by Iraqi Jews. This is the story of his search for the source of the songs he loves and the performers who still sing and play them. Presented by international filmmaker Marsha Emerman, with Prof. Michael Weingrad. 7:30-8:45 p.m. at the MJCC.
