 Aroch invested his time in many interviews in order to emphasize his interest in formalism, in its forms and in its way of constructing a painting.However, many of the abstract forms and images were the result of the process of “concrete abstraction,” in which the forms preserved, for Aroch, their symbolic significance.The painting technique which Aroch created, which included doodling, engraving, and “scribbling,” alongside of rational abstract painting, influenced a number of painters identified with the “Want of Matter” movement, most notably Raffi Lavie, who was viewed, along with Aviva Uri, as paving the way for new Israeli painting.
