'oh oca o' is an exploration of perception. Throughout the album different aspects of the way we perceive the world are explored: from the right-left sidedness of the brain, to notions of continuity and the way our mind perceives objects. Several new stereo techniques are developed and explored, and each track divides the sidedness of our brain's attention in a different way, opening new perceptual experiences.
Another theme of the album is the exploration of both the micro and macro worlds of sound. Everywhere is constant evolution, from the global level right down to microscopic manipulations. There are many layers of fine timbral nuance throughout the album, so for best results, listen through headphones.
