The first release from Sleep Research Facility since 2012's "Stealth" (Cold Spring) is inspired by the deep sea ocean floor. The Canadian-based composer explores notions of awareness and perception in the sub/unconscious listener. Focusing primarily on sound bereft of rhythm based energies, SRF provides an environments wherein the music adds texture to the silence. Using form without structure and concentrating on space as opposed to narrative, SRF entertains the idea that music can reside in the very fabric of sound itself. The brand new material here was created specifically for this split release.

Taking inspiration from the beautiful, but often harsh landscapes and environments of his home on Anglesey, North Wales, Llyn Y Cwn has built on the nautical theme of "Du Y Moroedd". These tracks are based on field recordings relating to the ocean, and could be seen as a companion piece to the album. 'Dale Dawn' features a recording of the dawn chorus made from the floating pontoon at Dale, Pembrokeshire. 'Pebble' includes the sound of waves crashing on a Dorset cobble beach, thousands of rocks colliding in chorus. 'Doppler Current Profiler' is based on the sound of an ADCP, an acoustic sonar instrument used to measure water currents - a 600Khz ping slowed to a heartbeat.
