The Musical Walls project is a unique interactive sound installation guiding us through the rich musical past and vibrant present of Erzsébetváros, across various sites in Budapest’s 7th District. The aim of this project is to bring residents and visitors closer to the district’s musical heritage through public artworks, linking past and present in harmony. For this purpose, the renowned art collective, Metrum Ensemble, has been chosen as the creative force. Since their debut in 2012, Metrum Ensemble has been a distinctive presence in Hungarian music, reviving the memories of Erzsébetváros through their unique artistic vision, with a special focus on Jewish traditions, cabarets, and coffeehouse music, as well as the district’s working-class and religious musical heritage. Through interactive Sounding Memorials this rich legacy becomes accessible to all, with QR codes allowing people to acces to the curated musical selections on their mobile devices.
