Urbásek’s work during the 1960s still showed the waning influence of informel as well as increasingly reflecting his interest in lettrism and geometric abstraction. In the 1970s his art was characterized by clean, sophisticated geometric compositions, and in the 1980s this clinical geometric precision made way for a different manner of expression, which can also be seen in the canvas entitled O-85-08. The surfaces of Urbásek’s paintings from this period became more prominently sculptured and structured, as geometric shapes were penetrated by diagonal brushstrokes in the form of cross-hatching. In this late period, Urbásek’s works shifted towards darker and radically monochromatic forms of expression, producing paradoxical similarities with the formal aspects of surface structures that were typical of informel – an approach that Urbásek had radically rejected early in his career as he shifted towards geometric forms.
