Hans de Vries concentrated on the study and registration of processes and appearances that occur in and are created by nature. De Vries was a close observer, an onlooker, an eyewitness, whose aim was to discern and document the relationship between man and his natural environment. His practice has been referred to as “micro-emotive art”, a term coined by the Italian artist Piero Gilardi. Hans de Vries Works 1968–1975 is De Vries’s first exhibition since he stopped producing art at end of the 1970s. It is a retrospective of all the publications and book-related works including parallel articles and essays about his practice.
