This year's Perth Festival takes us to the stars, with many events in the program inspired by stories of the cosmos. The West Australian Symphony Orchestra's concert Music of the Spheres included music from Australian composer Richard Mills' forthcoming opera Galileo, inspired by the life of the pioneering Italian astronomer Galileo Galilei.Also, Aboriginal dreaming stories inspire bold new theatrical work being staged under — and among — the stars, and Palawa writer Nathan Maynard and Māori writer Jamie McCaskill take us on an adventure across the sea and through the stars and spirit world in Hide the Dog.
