"My first concert - apart from Beethoven at School and Satie at the opening of my exhibition in Kleve in 1960 - was at the gallery Parnass in Wuppertal in 1963. Dressed like a regular pianist in dark grey flannel, black tie and no hat, I played the piano all over – not just the keys – with many pairs of old shoes until it disintegrated. My intention was neither destructive nor nihilistic. “Heal like with like” – similia similibus curantur – in the homeopathic sense. The main intention was to indicate a new beginning.. ..or simply a revolutionary act. This was my first public Fluxus appearance."
