Spring 2005"Frühlingsknacken" was an Exhibition in an uninhabited flat, together we were 7 exhibitors: Florian Tampe, Naomi Hennig, Knut Herrmann, Béla Janssen, Magdalena Krawcewicz, Michael Schmeichel, Marthe Krüger, Juliane Matthaei. The endless tape strip was guided through one room. recorded bird singing were played. Unexpectedly the tapes strip turned round and we could hear strange sounds because the tape was played backwards.
