AGGREGATE FESTIVAL 2025

The AGGREGATE festival expands its focus beyond purely automated organ music to reflect current developments in the new organ movement. Celebrating its fifth anniversary, the festival presents a comprehensive overview of the latest international positions through performances at several iconic Berlin venues: the Chapel of Reconciliation, Kaiser Wilhelm Memorial Church, with the addition of Sankt-Hedwig Cathedral as a new organ venue. The program features both new compositions and existing works, a site-specific installation, and introduces gamut inc's new wind-dynamic modular organ to the contemporary organ landscape.
