In 1998, Carsten Nicolai, also known as Alva Noto, visited a sound installation created by Robert Lippok for a group exhibition in Weimar, Germany. Soon after, he invited Lippok to release music on his label raster-noton. »Open Close Open« was released in 2001 and marked the beginning of Lippok's solo career. Before, Lippok had already played in Ornament und Verbrechen (with his brother Ronald Lippok) and To Rococo Rot (with Ronald Lippok and Stefan Schneider).

The title of the EP is a linguistic reference to the instructions found on everyday objects. In fact, the sound of birds or a closing door can be heard. Besides field recordings, cultural fragments were used – including the sample of the famous Adagietto from Gustav Mahler's Symphony No. 5. – and integrated into three loop-based pieces, that have been praised by Fact Magazine as »a masterclass in collage, looping and tactile processing.«

The source material for »Open Close Open« initially served as a soundtrack for a video by Takehito Koganezawa, a visual artist from Japan. For this remastered vinyl reissue, Lippok revisited the original sound material and produced a new track called »Licht«.
