True to the conceptual intrigue of Armajani's work, in which monumentalization can be found and represented in the mundane as well as in poetry often unfold architecturally, Sound Towers (1970) is conceived at the moment when the artist began thinking about architecture as a material for art. In this case, Sound Towers details a project to build a tower in which a moment of silence precedes a moment of sound, as sound is generated by the movement of air through the hollow towers.
