Over two days at De Appel, ‘Collective Study in Times of Emergency’ brought together texts, voices, music, films, artworks, digital images, and printed materials – creating a space where individual and collective research and archives came into dialogue. This video reflects on moments when international solidarity with the Palestinian resistance intersected with solidarity against South African apartheid. These encounters revealed the archive not just as a site of preservation, but as a living network – crossing borders of geography, time, and form. What futures do these archives hold? What kinds of solidarity will we imagine and practice in a distant future, once these materials have decomposed and become part of us? As Matter Speaks moves across different traces of the 'Collective Study' programme, summoning a space between permanence and fragility, where archives circulate endlessly.
