The Occult Architecture of Moon Duo’s fourth album - a psychedelic opus in two separate volumes released in 2017 - is an intricately woven hymn to the invisible structures found in the cycle of seasons and the journey of day into night, dark into light. Offering a cosmic glimpse into the hidden patterning embedded in everything, Occult Architecture reflects the harmonious duality of these light and dark ener­gies through the Chinese theory of Yin and Yang. In Chinese, Yin means “the shady side of the hill” and is associated with the feminine, darkness, night, earth. Following this logic, Vol. 1 embraces and embod­ies Moon Duo’s darker qualities, in the heart of winter in the Northern Hemisphere. According to guitarist Ripley Johnson, “the concept of the dark / light, two-part album came as we were recording and mixing the songs, beginning in the dead of winter and continuing into the rebirth and blossoming of the spring. There’s something really powerful about the changing of the seasons in the Northwest, the physical and psychic impact it has on you, especially after we spent so many years in the seasonal void of California. I became interested in gnostic and her­metic literature around that time, especially the relationship between music and occult qualities and that fed into the whole vibe.”
