September 5th 2021 – Heilbron & Hvizdalek DOUBLE CONCERT – simplicity

The Australian-German musician Jonathan Heilbron overlays, interweaves and moves the sounds of four portable chord organs. These well aged instruments bring their individual sound and playing characteristics (microtonal fluctuations, noises, dynamic blurring) into the musical process. The sound result is simple, meditative and highly complex at the same time.

Agnes Hvizdalek is conceiving a new work for the sound space of the Ruprechtskirche. With curiosity and persistence, the voice virtuoso always moves to the limit of the inhumane and finds materials and opportunities that become good friends in the process of getting to know each other.

Each performance takes about 40 minutes, there will be a break.

Jonathan Heilbron – chord organs
Agnes Hvizdalek – composition, voice
Daniel Lercher – sound engineering
