**Limited edition of 500 copies on heavy clear vinyl in clear plastic cover** Based around digital lock grooves this work by Digital Terrestrial is also observed by composers like Steve Reich (Minimalist/Systems music) and will eventually be performed by a String Quartet. It could be thought of more as a piece of conceptual art rather than just a piece of music. This vinyl only release could well be described as 'a lock groove record without the lock grooves...'. Playing time over 38 minutes.
