Horizon is sublimely beautiful, evocative music written for and recorded by the celebrated Australian Chamber Orchestra. Adams writes:?"There are two horizons. The visible horizon. And the true horizon.... As we scan the horizon we measure not only space, but also time. 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?." Composer John Luther Adams' music has won a Pulitzer Prize and a Grammy Award (and a number or Grammy nominations) and has been performed by such prominent ensembles as the New York Philharmonic, the Chicago Symphony, the Los Angeles Philharmonic, the Seattle Symphony, and the JACK?Quartet. "John Luther Adams... one of the most original musical thinkers of the new century." (Alex Ross, The New Yorker) "His music becomes more than a metaphor for natural forces: it is an elemental experience in it's own right." (Tom Service, The Guardian) "His music perfectly echoes the landscape he loves: impersonal, relentless, larger than human scale, yet gorgeous." (Kyle Gann, Chamber Music Magazine) The Australian Chamber Orchestra (ACO) is a unique, highly lauded string orchestra led by Richard Tognetti. It tours the world, performing works from all periods of Western classical music, and has recordings on ABC Classics, BIS, Hyperion, Chandos, Sony, and other labels.. "ACO... invigorating and highly cultivated-a breath of fresh cultural air" (Gramophone) "This terrific string ensemble... seems to shine at anything it undertakes." (San Francisco Chronicle) "ACO... The finest chamber orchestra on Earth (The Telegraph, UK) "An orchestra that, by any standards, is one of the wonders of the musical world today." (The Guardian)
