Little known outside Sweden, Olle Baertling produced hard-edged geometric paintings and sculptures from the late 1940s until his death in 1981. The works use a purity of line, color and composition in the tradition of Malevich and Mondrian to help the viewer access a higher state of being, a metaphysical world beyond decay and daily experience. In Demonstration, Dahlgren paints reproductions of Baertling’s paintings on plywood then mounts them on poles.
