Following on from the psychoacoustic concrète of Outside Ludlow/Desert Disco LP (BT 075LP, 2021), Sam Dunscombe returns to Black Truffle with Two Forests/Oceanic. Dunscombe has been active in recent years on multiple fronts, including as a key member of the Berlin community of Just Intonation researchers and practitioners; working with composers like Taku Sugimoto, Mary Jane Leach, and Anthony Pateras; and the release of Horatiu Radulescu - Plasmatic Music Vol. 1 (the result of many years performance research into the thought and music of this seminal Romanian spectralist). "Two Forests" begins in a central Californian sequoia grove. Bird songs and buzzing insect life are treated with a variety of time-based processing methods (slicing and recombination, primitive granular synthesis, delay, and so on), which strip the field recordings of their linear, documentary character, reframing them in an enchanted web of traces and echoes.

Analyzing the pitches found in the original recordings, Dunscombe used them to generate a large Just Intonation pitch set. These tones are woven slowly into the field recordings, gradually building in density and complexity until the forest has been transformed into an unreal space of infinite proportions. On "Oceanic," several recordings of different beaches fade in and out to create a texture both homogenous and constantly shifting in both the rhythm of the waves and each recording's sense of depth and distance. Tones relating in simple ratios to the average rhythm of each beach float over each other, coloring the white noise texture of the field recordings with shifting hues. In both pieces, Dunscombe forgoes the easy consonance that bogs down much contemporary ambient music for a richer harmonic array informed by extended tuning practices and spectralism.

The end results suggest a hitherto undreamt-of meeting of Horatio Radulescu's undulating sonic masses and the discreetly processed location recordings of Irv Teibel's "psychologically ultimate" environments. Looking beyond the insularity that can afflict experimental music culture, Dunscombe's work is a moving argument for the healing power of expanded approaches to sound and music. Even outside of a psychedelics-assisted therapy, frequent immersion in Two Forests/Oceanic is almost guaranteed to produce beneficial psychological results.
