Among others, in 1962 Aroch attended an exhibition of the works of “Pop Art” artists, including Robert Rauschenberg and Jasper Johns. The use by American artists of “modified” Ready-made objects as part of their artistic works, and the abstract styles known as “Tachisme” and the French “Informel,” combined in Aroch's work in a delicate style that became known as “concrete abstraction.” For Aroch and his interpreters the meaning of this style was a combination of figurative images that had a symbolic meaning for the artist, and design as abstraction in order to create a new, independent form.
