Close To mark the 20th anniversary of the National Museum of Australia, Slava and Leonard Grigoryan have selected 18 objects from the museum collection and responded to each with a new composition. The objects trace the history of Australia over the past 60,000 years. From an ancient artefact from Arnhem Land, to convict love tokens, a protest sign, and even Sir Donald Bradman's cricket bat, take a journey through each of the objects with Alice Keath and hear the musical responses by the Grigoryan brothers.
