With the "Verstärker" series, Gerold Miller realized free-standing sculptures since 2016. These bodies, which rest firmly on the ground, are reduced to their height, width, and depth and thus visualize the primary conditions of sculpture: material, mass, and dimension. Their characteristic formal clarity opens them up to the infinity of space, plumbing its imaginary boundaries. Their univocity, varying dimensions and material textures give the sculptures a distinct physical and sensual presence. The reflective bodies of the "Verstärker," made of metal, give rise to surprising visual impressions in which floor, ceiling, opposing walls, or even outdoor spaces interconnect in irritating ways, reordering the space in an almost labyrinthine fashion. They involve the casual viewer in this process via their reflective surfaces, allowing him to become an actor for a fleeting moment.
