A long evening entirely devoted to low frequencies: three sets explore the world of bass instruments and voices across their full sonic range.

In the first set, Beatrix Wagner plays the rare contrabass flute in G – an instrument that once also inspired Luigi Nono's duo A Pierre. With Gerald Eckert playing electronics, two pieces from 2024 are performed: Alessio Rossato's si'páame and Gerald Eckert's Verschränkung - ins Offene. Both works explore the instrument’s distinctive sonority.

Next, featuring the American singer Andrew Munn, comes Horațiu Rădulescu's These Occult Oceans (1981): a pioneering spectral composition for solo bass voice and up to 17 pre-recorded bass voices, using specialized vocal and consonant techniques to unleash the sonic power of overtones and undertones.

The evening closes with BONECRUSHER, an ensemble of ten trombones and two percussionists. Active as a fixed group since 2020, they have developed their own sonic language, moving between sculptural noise drones, collapsing cascades of brass, and delicate weavings of breath, tone, and overtones. The physical and acoustic possibilities of the instruments are pushed to their limits, the archaic sound apparatus, so to speak, put through a "bone mill," pulverized, and given new breath. Within this, Ellen Arkbro's expansive Nightcloud Variations, with its long-sustained, justly tuned tones, unfolds alongside Matthias Muche's Gleiter.
