»There are things under the roof« - this announces the wealth of material from which object artists draw; In this exhibition not only do different materials come together, but also different artistic personalities.

Daniel Spoerri invited Barbara Räderscheidt. She in turn took up the friend principle »No Art without friends« and addressed nine other artists with whom she has carried out many joint projects over the past decades and some of whom have a direct connection to Daniel Spoerri. They visited his class at the Cologne Art Academy, where he taught in the late 1970s. Projects like the Musée sentimental de Cologne or the legendary eat art banquet Hommage à Karl Marx (a homonymous dinner dedicated to the then director of the university – a namesake of the famous capitalism critic) – these were spectacular events that continue to influence the art and museum world today. Of course, they also shaped the understanding of art of everyone involved and brought with them the experience that joint projects increase the power of the individual. In this years Hadersdorf exhibition, collages, assemblages and drawings by Jojo Wolff, Heribert Schulmeyer, Gerd Kuck, Theo Kerp, Max Zimmermann, Stepahn Andreae, Manfred Lohmar, Herbert Rosner, Petra Siering, Daniel Spoerri and Barbara Räderscheidt enter into dialogue.
