Pulitzer Prize-winning American composer John Luther Adams wrote this piece for the Australian Chamber Orchestra. Inspired by his recent relocation to Australia and his travels across the continent - from the Northern Territory and the Red Centre all the way to Tasmania - 'Horizon' is an immersive audio experience exploring the relationship between the visible horizon, with its trees, its mountains and its human structures, and the true horizon: the enveloping circle where the sky meets the earth. How long might it take us to traverse that distance, from where we are to as far as we can see? And what lies beyond that edge of the known? The Australian Chamber Orchestra brings its passion, its virtuosity and its vibrant energy to this exquisitely unique musical experience.
