Two dancers dressed in black, with one white spotlight following them on the empty stage. Stripped of elaboration, the performance focusses on their body movements, how the dancers flow, defy gravity and interplay with each other, reinforced by the shadows created from the white light.  Every movement is important; each flexing of a muscle, each twitch of an eyebrow.  

 In the same way, thin delicate lines, like pen drawings, are translated into three dimensions by Knopp Ferro, or perhaps four if movement is added, with another layer behind from the shadows that dance with the lines.

Alexander Calder used slender metal wires to connect his bold shapes together; in the work of Knopp Ferro it is the thin wires themselves that define the sculptural forms, defy gravity and create the interactions and movements with the delicacy of pen-strokes, floating in air as mobiles or projecting, quivering, from the walls and, sometimes, within simple deep boxes which frame them just like the stage of a theatre frames the dancers.  

The Austrian artist Knopp (born 1953), who lives and works in Munich, combines his background in sculpture and in performance, having set up the artist collective Jet Ferro and worked with the performance theatre Bumper to Bumper, in his elegant and unelaborate sculptures, allowing the wires to create their own three dimensional forms, with an occasional splash of colour in the background, as simple and as beautiful in their own way as the two dancers.
