A manifesto is characterised by the public declaration of goals, intentions, values, wishes, and thoughts. There are countless manifestos; they have been written down, read out, spoken, proclaimed, and often enough archived. The student set out on a search. He wanted to read the manifestos of those who, as black people, experienced slavery during and after the colonial era, were deprived of their freedom, and lived under inhumane conditions. How were they able to preserve their dignity? Their manifestos could give new strength to black people who are still suffering from the consequences of slavery and colonization today. Despite an intensive search, he was unable to find any manifestos that corresponded to his ideas. It seemed as if the question of the goals, values, wishes, and thoughts of enslaved people remained unanswered for him. A great emptiness. But then he discovered the Worksongs that fill this emptiness with their unique sound. It is the absence of something that was once there, but seems invisible and unattainable. With the help of the Worksongs, the project aims to show this absence and make it accessible. Designing to create space. Because absence draws attention to its existence, in which it persists.
