We all have our own ways of passing time on our daily commutes. Some people read, others try to sleep, and many listen to music or play on their phones.

Karl Bang's paintings are unique because he combines totally different styles of painting within the same format. It is very difficult to design a balanced composition with realistic elements that are juxtaposed with flat colors and patterns. The faces of his subjects are painted realistically in the Western tradition with subtle gradations of color; while, his figures and costumes vignette into abstracted shapes, lines, flat colors and patterns that reflect Karl's background in China. It is as though there are different visual languages being spoken within his paintings.
