On a recent weekend, a group of local artists, writers, clothing designers, and others set up shop in the backyard of the Ridgewood rock club TV Eye for a “Palestine Benefit Market,” with the goal of fundraising aid efforts for Palestinian refugees in Egypt. Organized by a pair of artists named Katie Grossman and Lia Kantrowitz, the group recruited collaborators out of a handful of affiliated leftist activist groups like the Gaza Mutual Aid Collective, the Ridgewood Tenants Union and Bushwick Mutual Aid.
