BioBorn in 1969, Sieverts works primarily as a tour guide. He attended the Düsseldorf Art Academy and has been employed as a shepherd as well as in architecture bureaus in both Cologne and Bonn. Sieverts has guided locals and tourists through the grey zones of sprawling urban areas and conurbations since 1997 through his alternative urban travel service, Büro für Städtereisen. With the help of sophisticated spatial sequences, he draws scenic connections between environments which otherwise are considered as extremely disparate. He then develops visions and continuative interpretations of the investigated landscape and settlement formations. Sieverts has also held the lecturing and other positions in Nantes, Leipzig, Kassel, Portland, Maastricht and Hamburg. His Solo exhibitions and co-operations have taken place in Germany, France and the USA. The artist currently lives in Cologne.
