A thin ribbon of green viscosity slithers under a flautist’s door. It slides along walls and meets other slender ribbons – deep, glistening chestnut from the folk club, vivid scarlet from a classical concert in the town hall and vibrant, earthy umber from the mellow notes of Miles on a stereo. Together they dance solemnly, rising up, coiled together in a strange braid of colour and light, and then part to pursue their solitary tasks. They are creatures of great beauty and ingenuity.
