I first listened to Gurrumul’s final album Djarimirri (Child of the Rainbow) on my way home from a writers' festival organised by the small Queensland town of Boonah where I ran a workshop earlier this month. Driving through country dry and sparse - trees, grass, granite peaks, a long straight road, farms, cows - I was far from the sea and sky and crocodiles of Gurrumul's Elcho Island home. But the songs were here too.
