Peter Sculthorpe (born April 29, 1929) is a noted Australian composer from Launceston, Tasmania. He is known primarily for his orchestral and chamber music, such as Kakadu (1988) and Earth Cry (1992), which evoke the sounds and feeling of the Australian bushland and outback. He has also written several string quartets, using unusual timbre effects, and works for piano. Sculthorpe's catalogue consists of more than three hundred and fifty works and, apart from juvenilia, a good part of it is regularly performed and recorded throughout the world.
