His graffiti are minimalistic but charged with aesthetic power. The sparse, incisively charted lines compound to create complex meaning and capture the essence of the depicted motif. The Swiss artist Harald Naegeli rose to worldwide fame in the late 1970s as the »Sprayer of Zurich «. He devised graffiti to lambast Zurich’s sterile, unwelcoming urban appearance, as well as the city’s politics and treatment of the environment. Convicted on multiple charges of criminal damage, Naegeli absconded to Germany, whereupon an international warrant for his arrest was issued. Returning to Switzerland, he had to serve a six-month prison term. Thereafter, he lived and worked mostly in Düsseldorf. He began writing philosophical and mutinous dispatches about his latest graffiti and drawings as »Harry Wolke« (Harry Cloud) to the »Freunde der Wolke« (Friends of the Cloud) as a way of slightly prolonging the life of his ephemeral art, his »utopias«. Returning to Zurich in 2020, he sprayed over 50 »Dances of Death« throughout the city. The Canton of Zurich sued him for damages; the city awarded him the City Art Award.
