This is the show Heidi has been waiting to bring home: the Heidi Joubert Chaos + Peace Band headlines the main stage in Hammer Park — her own band, her own songs, closing out the Hammer Sommerfestival’s final Saturday night.
Chaos + Peace is Heidi’s debut album — every song written and produced by her, recorded with a New York all-star band, blending percussion innovation with soulful songwriting: rhythm, melody, and heartfelt yet humorous storytelling from the Cajon Queen who has spent twenty years making the box speak. Live, it becomes something bigger — singer, songwriter and band leader at once, with the cajon at the centre of it all. The album is here if you want to arrive already singing along.
The setting could not be better: Hamburg-Hamm’s free neighbourhood festival, back for its sixth year — ten days of music and culture built by more than forty local groups together with the KNUST music club, with the main stage in Hammer Park from 26 August.
Saturday 29 August 2026 · Hammer Park main stage, Hamburg, Germany. Free entry — bring everyone.
