From 2005 to 2016 Stefan Goldmann engaged in artistic exchanges with some of the leading labels of the time. 'IOU' collects those tracks, previously released to critical acclaim by labels such as Perlon, Cocoon, Mule Electronic and Innervisions. Sleepy Hollow, Phraselab and Yes To All were all crucial offerings at a time when the scene was looking for a way out of minimal. IOU also entails material produced under a contract with Music Man Records under the Barricade moniker in 2004/2005, but remained unreleased at the time. Tracks such as Radar Opaque, Aleko and Frantic might have foreshadowed some later developments in techno, but only saw the light of day with a delay of several years. Make up your own mind.
