Demonstrators muffled the sounds of the Philadelphia Orchestra over the weekend in a protest of the company’s upcoming tour in Israel.

Palestinian novelist Susan Abulhawa started protesting the orchestra well before the recent protests in Gaza garnered headlines when the Israeli military killed more than 60 Palestinians in one day, coinciding with the opening of the U.S. embassy in Jerusalem. Abulhawa is part of the coalition that put on the Saturday event and campaign, organizers included Workers World, Black Lives Matter, Jewish Voice for Peace, Adalah NY, Philly BDS, Black and Brown Workers Cooperative, to name a few.
