Detached from any reference to concrete representationalism, Bach's motifs are reflections on fundamental questions of pictorial architecture: in his pictorial compositions, depth meets colour surface painting, and two- dimensionality meets spatial constructions.

The exhibition shows large-format works whose compositions are characterised by the division of the pictorial space into two halves. A picture-within-a-picture principle in which each side stands on its own and yet corre- sponds with the other half. In this way, the layered colour and pattern surfaces create the illusion of a more or less deep space.
