Wings

a feedback performance

One loudspeaker and three microphones are placed opposite eachother. The volume is turned up, and acoustic feedback occurs between the microphones and speaker. Three performers manipulate the feedback by shifting foam-board panels around, creating new spaces with every movement and therefore also changing the space, in which the feedback can resonate. Depending of the placement of the shields and of the pitches of the feedback, the sound is processed differently by the computer (all pictures © Silvana Torrinha).
