Peter Sculthorpe's career has been one of remarkable unity of vision and consistency of purpose. From the start, he set out to create a music which, while universal in content, would be specifically Australian in its idiom. At the time he was growing up, this was not an over-simplistic aim, especially when Sculthorpe looked at the music then being written in Australia and saw that, by and large, it was hopelessly dependent on European manners and cultural traditions that could only be acquired at second-hand. Australians were then, and still are, in the process of self-discovery; the best Australian artists have learned that their own country can provide them with richer material for their work than can distant Europe. Painters, especially, have found the extraordinary Australian landscape, where trees shed their bark instead of their leaves, and prehistoric animals roam in a red desert, a potent source of inspiration. Even in the 19th century the painters of the Heidelberg school, in responding to the glaring Australian light, produced work quite different in feeling from the French Impressionists who were their models. In the 20th century a true national school has come into being, whose major figures have all helped to define the Australian landscape's peculiar strangeness – Lloyd Rees, Russell Drysdale, Fred Williams, Arthur Boyd, Sidney Nolan.
