A Joyful Revolution takes us on an inspiring journey through music creations for young audiences. Focusing on nine projects presented at the BIG BANG Festival - a unique laboratory for experimentation with music and sound - this publication offers an in-depth and kaleidoscopic reflection on innovation within the musical offering for children. This collection of texts highlighting original processes and daring artistic proposals also includes essays by artists and thinkers that together form a vibrant anthology on childhood, anarchy and music.
