Camera Obscura by Trigger plus Jérôme Noetinger

Trigger is an acoustic wind instrument trio working in the context of
experimental music. Together they aim for the creation and shaping
of a homogenous overall sound. The three instruments function as
generators of noise and sound and blend together in a complex sound
mass, which is permanently moving, changing and renewed. By
using advanced playing techniques such as circular breathing,
multiphonics and a vast palette of air sounds the instruments are
removed from their traditional context and resemble electro acoustic
sound sources, which interact by imitating and contrasting with the
specifically use of timbre, density and dynamic.
The players react to each other immediately, allowing fast changing
sound constellations with a compositional awareness for structure
and duration.
