Clark controls his anger with the professional boxer's precision. His canvas build on very large areas of courageously applied oil paint, the divisions of which are mostly horizontal. The tonal gradations of the original individual colors are deliberately underemphasized. Thus, the primary character of each division relies on boastfully conspicuous brush strokes to stress an ownership of space that suggests either form or movement. There is an unconscious life in these signals that is entirely painterly. Erupting from the unplanned design, the occasional splashes of paint create desolate as well as explosive landscape effects. The line-surfaces bristle with hostility. Mostly over-large, the compositions seem admirably suited for sublimating passions otherwise difficult if not impossible to control.
