Postscript III-V (Berlin) is the last iteration from a work that I had been performing, constructing and deconstructing for many years, hahn/huhn (2003-2016). The genesis of hahn/huhn came from a piece of prose I wrote in 2003, Who Is Reinhold Hahn?. As prose writing and subsequent work, hahn/huhn was constructed as a composite of fragmentary biographical information, historical markers and monuments beneath and above the city of Berlin, and loosely driven by principles of dérive and psychogeography. In 2005 the work moved more into spoken narration, which gradually enveloped assembled materials and images to accompany it. These ranged from live performances (to a public vis-à-vis or remotely, via telephone and mail-art), printed matter (activated via performance or left as documentation, residues, from performances) to lightbox, slide and film installations. Since 2013 hahn/huhn was presented under various iterations of Postscript (Berlin), as a synchronized slide to spoken narration installation.
