Christoph Heemann, a German sound craftsman also known as Mirror with H.N.A.S. and Andrew Chalk. The independent solo work "Perception & Association", which was announced on CDr from [Dom Bartwuchs] operated by himself in 2015 and is currently out of print and soaring, has been made into a congratulatory LP from the famous place [Robot Records]! The A-side of the tribal drone, which gradually increases in thickness, and the B-side, where the metallic roaring collage sound is completely wrong, are both quite powerful. A good work that inherits the spirit of early electro-acoustic writers such as Jacques Lejeune, Eliane Radigue and Jaap Vink. The front cover is designed by Ruth-Marie Adam and the back cover is designed by Fritz Martin.
