Moon Duo’s Circles was birthed from a long period of winter isolation in the Rocky Mountains. The album was primarily recorded at home in Blue River, Colorado in February 2012, with additional recording taking place at Lucky Cat Recordings in San Francisco in April. Like it’s predecessor, the album was mixed at Kaiku Studios in Berlin. Inspiration for many of the songs’ themes, as well as the album title, came from Ralph Waldo Emerson’s 1841 essay “Circles” on the symbol and nature of “the flying Perfect.” From the opening lines: “The eye is the first circle; the horizon which it forms is the second; and throughout nature this primary figure is repeated without end.” And so it goes. Rust never sleeps.
