Space, the final frontier. Yes, we all know the tag line from that famous sci-fi franchise, but it is a phrase which is also relevant to music. Many artists and composters, songwriters and creators are so focused on filling the void in front of them with all manner of sounds and musical substance that they often miss a trick. That trick being that silence itself, when correctly framed, can be a useful tool too. And if such artists are the equivalent of oil painters covering the whole canvas with vibrant musical colours and sonic images, then Christopher Sky is the water-colour artist using the sleekest of lines and the bare minimum washes of paint to turn the white background into the desired design.
