But differently from these, Vogel constructs acoustic forms and temporary structures that are inspired by more abstract images or concepts. In both cases what is of primary importance is the involvement of the viewers who activate and influence the works and so undergo a heterogeneous and very complex sensorial experience. Vogel’s sensitive structures are, in fact, equipped with a system that can influence itself to create a mutable effect based on the incidence of sound, movement, light, and shadows.

The form of his Interaktive Objekte works follows the function of each object: the sound objects, the light reliefs, and the kinetic sculptures highlight their electronic components and visualise the sensors, amplifiers, loudspeakers, and LED lights that allow active interaction. The dialogue/game between the subject and the object gives rise to an exchange of information, an alternation of actions and reactions that alter the perception and reception of the sensorial data, an exchange that varies in intensity or duration according to the various kinds of objects. For example, the atonal schemes and the polyphonic ones differ in their repetitive or more changeable sequences to generate a field of occurrences and possibilities that can be infinite, just as the relationships we make with other people can be infinite.

The show is backed by an important monograph in Italian, English, and German, with critical essays by Alberto Zanchetta, and a wide selection of works, projects, photographs, and documents that record the fifty years’ activity of the artist.
