It's a piezo-painting: fixed on the canvas to be mistreated as microphones, piezo speakers were the sources to sample the sound of Marcus Heesch's painting process and alter it as part of an audio-visual improvisation.
Knut Aufermann [sampling, electronics, feedbacks] and Joachim Zoepf [bass clarinet] never met before... now, stop, look and listen to their free improvisation in an interdisciplinary context, that celebrates its 25th anniversary: "live-tempera" at work during the private opening of the exhibition "iTempera · interdisciplinary painting in eggtempera" at GOETHE45 in Bremerhaven on 11th of July. In the backyard, the live-painting was shown as large scale projection on the wall in realtime.
You might want to make use of proper headphones, 'cause the sound is rich... and so is the improv.
Now here is the thing: playing the sound through the piezos back onto canvas, you'll recieve the rare kind of a whispering painting...
