"Double Layer(live)" is a modified live version of the sound-installation "Double Layer".
By turning on the fans, the microphones start to rotate. These sounds and the signals gained by piezo microphones placed on the fans, build the only acoustic source for this live performance. The original signals are modulated and adjusted via various effect units and mixers. By and by the sounds evolve through layers of feedbacks, played back noise, ventilator sounds and the natural resonance of the space. What we hear is a fragile structure always close to collapse. This is a special type of network or interaction - it raises awareness about the interplay between sound, space and movement in combination.
“Double Layer” functions as a cause and effect unite in a self-contained coupling, where an input gives an output that comes to influence the input again. This might be said to function as part of any system, production or network, shifting in degrees of positive and negative influence. Or as Brandon LaBelle describes the  communicational concept of feedback in “Acoustic Territories”:”This wavering oscillation[feedback] imparts an elemental dynamic of exchange of self and surrounding, as a deeply significant flexibility, and on a communicational level must be heard to give way to moments of intimacy and mingling, or intense proximity, as well as alienation and estrangement. Feedback is relationally productive precisely by functioning as such sensitive, tensing link prone to fluctuation.”

Mit dem Einschalten der Ventilatoren beginnen die darüber hängenden Mikrophone langsam zu rotieren. Die dabei entstehenden Geräusche bilden die akustische Grundlage für die Live- performance. Die Klänge werden nach und nach mittels diverser Effektgeräte und analoger Klanggeneratoren manipuliert und verfremdet. Die Performance endet dann mit dem Abschalten der Ventilatoren.
