Trümmer auf Trümmer is the exhibition of Kaba Hat’s 45 days long residency at Apartment Project,Neukölln, Berlin. The name of the exhibition, Trümmer auf Trümmer( Rubble over Rubble) is simply a connection to our visits to the ruins of garden colonies close to Treptower Park. We have come to explore this area during our walks and visited ruins a lot. It became a part of our talks. The final works exhibited at the exhibition was a collective yet personal fanzine and a wheat-pasting poster installed on the gallery window. The papers used in the fanzine were made during the residency at the studio/gallery, recycling collected papers and some thrash. The main theme of the work is our walks and our becoming collective process in relation to the ruins.
