Neighbourhood Voices is a participatory cultural project in Brussels that aims to strengthen dialogue, encounters, and civic participation in local neighbourhoods. Activities take place under the big top of Les Nouveaux Disparus, temporarily installed in different municipalities to create an open and welcoming cultural space in the city. The project offers two participatory workshops bringing together around ten residents from diverse social and cultural backgrounds. Combining theatre improvisation and musical awakening with collective intelligence methods, the sessions invite participants to share experiences, develop mutual listening, and explore the realities and challenges of their neighbourhood. Participants then attend the theatre performance Le Songe by Jamal Youssfi, which addresses migration, solidarity, and mutual support. The performance is followed by a discussion with the artists, linking the themes of the play with participants’ lived experiences. By encouraging encounters between neighbours, artistic expression, and civic dialogue, Neighbourhood Voices seeks to foster collective dynamics and strengthen local social cohesion.
