LeWitt was seminal in establishing the notion of `Conceptual art? during the 1960s. This work is one of a number of highly coloured wall pieces he made in the last years of his life. Described simply as `curved and straight coloured bands?, it includes seven vibrant colours to create an overwhelming chromatic environment that envelopes the viewer. Nine weaving bands interrupt vertical lines and add a sense of playfulness. Although this dynamism suggests an element of chance, LeWitt?s works are created according to precise instructions that regulate details such as the sequence of colours and width of bands.
