“Music is something I’ve never been able to disconnect,” says Baz Luhrmann. “The application of music can be done in a very supportive background way or in it can be used in a very foreground, demonstrative manner.” David Hirschfelder composed the score to “Australia,” and he hasn’t done work that most of us would know recently (a lot of TV), but he has written music for Academy-Award nominated films like “Elizabeth,” “Shine,” (he scored a nomination for each) and did wrote the score to Luhrmann’s “Strictly Ballroom.” There’s a lot of footage from the film in this featurette and damn it looks impressive.
