The ever expanding Noise Upstairs are hosting Partial Trust on Wednesday 11th August at The Riverside Cafe (Sheffield S3 8EN) and Thursday 12th August at Fuel (Manchester M20 4AN).

Partial Trust is a new collaboration between Richard Knight and Abigail Sanders, exploiting the relationship between unadulterated acoustic and electronic phenomena.

Sourcing from the hauntingly rich and pure timbres of the French Horn, Abigail emphasizes the natural acoustics of the instrument through multiple extended techniques, in a never-ending attempt to synchronize with (or combat against) the diverse range of sounds that the no-input mixer spews forth.

In a clash of regulated feedback, Richard harnesses the elusive delights of two short-circuited audio mixers. Intense and often capricious, these traditionally passive audio devices are teased into subversion, revealing eccentric and diverse personae.

Watch these two formidable and untrustworthy instruments combine and compete in a volatile frenzy of harmonics, as the respective controllers of their beasts explore the many characters of this unique instrumental duo.

Warning:  Ultrasonic tones emitted by the no-input mixer have been proven to cause fatigue and headaches.
