An anti-Israel organization staged a protest against the Israel Philharmonic Orchestra (IPO) on Sunday.

Adalah-NY, an organization that campaigns for the boycott of Israel, raised signs and carried cardboard guitars that read “apartheid” while chanting against Israel outside New York’s Carnegie Hall, causing a small disturbance on February 3. The protesters stood outside a fund-raising brunch for the IPO, which was followed by a performance.

On their Facebook page, the organization posted, “As the IPO’s wealthy supporters attend a lavish brunch inside to sustain its whitewashing of Israeli apartheid, we’ll be outside sustaining our love of justice with a small Palestinian brunch and music for liberation with the big freedom sounds of the Rude Mechanical Orchestra.”

Adalah accused IPO of being a political organization because it “represent[s] the State of Israel across the world,” and says that “[T]he goodwill created by these tours…is of enormous value to the State of Israel.”

In July, the same organization staged a protest outside New York’s Joyce Theater. During that incident, 50 self-described human rights advocates held what Adalah described as a “vibrant, musical protest” on the sidewalk to oppose the opening night performance by the Batsheva Dance Company.
