Typically for Bertil Greging works, is the exchange between the mischievous and the expressive on one hand, and the formal and minimalistic on the other. The artist allows different visual expressions and seem comfortable in different artistic directions; such as abstract, figurative and expressionistic and conceptual. Greging is an artist who grows chaos, both in his studio and in the imagery, but at the same time, it is clear through his works, that there is a wish to create an underlying order in this chaos. The expressive collages are places on “hard edge”-paintings, where the uncontrolled meets the controlled.
Greging works within a direct line of art history, the exhibition room and his own personal history. The humorous is present, but also traces of vulnerability and simplicity. At first, it may seem that the artworks have a factor of banality around them, but when looking at them more closely it gives an impression of being sensitive. By constantly balancing on the edge of different directions and combinations, Greging creates artworks that engage and challenge the viewer. A selection of his lasted exhibitions include: No More No Less, Rod Bianco, 2017. In 2015 he showed his works at Kunstnerforbundet and Tegnerforbundet (Oslo).
