Imi Knoebel is one of the most important European representatives of non-representational art, and he has devoted a lifetime to developing it. Around 1966, his first work was influenced by Kasimir Malewitsch's paintings and by Joseph Beuys, who taught him. Layering, sequencing, and stacking became his trademark techniques once he discovered masonite and its potential for creating large three-dimensional work. However, Knoebel also adopted a constrasting approach by producing extremely pared-down images which have no material form, to represent the immaterial. The catalogue of the exhibition provides a concentrated review of his early years; a newly-created complex of his works provides an insight into the essence of his multi-form work.
