The artistic oeuvre of Klaas Verpoest has its finality only intangible unstable carriers and mainly in the performing arts. Klaas Verpoest is active as a video-performer in numerous multi-modal improvisation performances. The combination and confrontation of multiple media through improvisation is the basis upon which the performers assume a fundamental equality of the components, sound, moving image, motion, either generated digitally. Working as a video-performer in improvisation performances results in an unique encounter with written [contemporary] classical music. Klaas Verpoest is not looking for a concrete visual translation of the composition, but he uses the different parameters of the composition and brings them together into a singular generative abstract image, which may be seen as an idiosyncratic visual response to the interpretation of the composition. The aim is to create an experience that at times illustrates a clear synergy between the picture and the sound – and at other times a strong contrast between these two experiences.
