AGGREGATE is a festival for automated and contemporary organ music organized by the Berlin-based ensemble gamut inc., founded by the composer duo Marion Wörle and Maciej Śledziecki. Since 2013, the ensemble has performed internationally using pipe organs that can be automated and music machines they developed themselves, and is considered one of the key figures in the New Organ Movement.

In the 2026/27 season, gamut inc will be our resident ensemble in our organ series. It will present, among other things, two evening concerts and will engage in an in-depth exploration of the automated Konzerthaus organ. It will enter into dialogue with BLACK SQUARE, the wind-dynamic modular organ developed specifically by gamut inc and Tony Decap. The spatial arrangement of both instruments in the hall, the computer-enhanced playing possibilities of the new concert hall hyper-organ, and the dynamic and microtonal capabilities of BLACK SQUARE enable sound sculptures and multi-layered compositions.
