Limited edition compiled to celebrate Hans-Joachim Roedelius's 90th birthday. The album "90" is inspired by Achim's 2-track Revox tapes (1968-80), capturing the essence of his *Selbstportrait* and collaborations with Dieter Moebius and Michael Rother. This is not an exhaustive retrospective, but a celebration of an extraordinary musical life. The hypnotic cycles are reminiscent of Terry Riley, offering intimate and innovative music, steeped in a fascinating historical context.
