Fueled by political passions, Midnight Oil’s Diesel and Dust is one of the most urgent rock albums of the ’80s. In the storming radio anthem “Beds Are Burning,” the band takes on its country’s exploitation of indigenous people. “Bullroarer” and “Dreamworld” are blistering tunes, as insistent and angry as they are catchy and inclusive. In contrast, “The Dead Heart” and “Whoah” create a slow and elegiac interpretation of country music, which Midnight Oil delivers as a ritual for a fading world.
