Realisation of the Niemeyer Sphere offered the opportunity to dedicate an exhibition to entitled “DONT/Conscious Decadence” to artists, musicians and design gallery owners. The cross-architectural exhibition, realised in close collaboration with David Ostrowski, Verena Glup, Kieran Kaul, Nan Goldin, Jett Rodgers, DJ Anthony Linell aka Abdulla Rashim and others within the very special spatial context of Halle 9, was experienced by many visitors as a total work of art, in which music, visual art and architecture came together.
