A participatory ‘Rights of the River’ gathering aboard Raybel, inviting participants to explore how we relate to rivers as living beings, moving beyond legal frameworks towards relationships of reciprocity, care, responsibility and cultural renewal. FORM will invite audiences to experience the Thames not simply as a waterway, but as a living collaborator with its own stories, relationships and agency, through sensory listening, storytelling and creative participation. Using underwater hydrophone recordings and guided exercises, participants will be invited to encounter the hidden soundscape of the river before joining conversations that connect ecology, culture, heritage and community.
