'We live in a world of musical undo and versioning.' R. Henke 'Collagen is an ideal release for the format, a mysterious band of sounds that are impossible to identify, close to home yet far away, buried in the past yet re-dredged. To listen to these clicks and cuts, these small drones, these buzzes and plastic ejections is to celebrate the under-appreciated and claim it as one’s own.' Richard Allen, A Closer Listen 'Collagen manage to maintain intrigue through its masterful compositional tactics. By smoothly transition between songs and portions of songs the album succeeds in creating droning sound conceptions.' Donovan Burton, Positively Underground 'Extracts of classical music and percussive exercise come warbling atop strands of drone, before decaying suddenly like soft objects dropped into acid. Strange analogue noises burst into view and then disappear, as though retracted in sudden, reflexive pangs of sound-editing regret. Collagen captures the anxious twitches of editing fingers – hands flying across knobs and hurriedly replacing one tape with another – as though Chemiefaserwerk is searching for something within the mess of archival capture.' Jack Chuter, ATTN Magazin 'Marseille-based sound artist Christian Schiefner is enthusiastically exploring the very fabric of sound [...] but unlike many noise-focused endeavours that tend towards a temporal staticity or overload, Chemiefaserwerk creates an eventful performance designed to artfully present a range of unidentifiable sounds whose fluid transformations and abrupt cuts carve the semblance of a narrative.'
