Berlin, August 1990, first post-wall Summer. Two friends, the locals Günter Schickert (krautrock maestro of echo-driven psychedelia) and gallerist Peter Unsicker perform a spectacular yet symbolically intimate interpretation of those epochal changing days by building a sound installation with a damaged piece of the Berlin Wall. They persuade the patrol "Feliks Dzierzynski" of the DDR army to transport and relocate a piece outside Peter's Wall Street Gallery on the Zimmer Strasse, in the borough of Mitte, where only a few months back the intact structure actually passed through. Once the wall was positioned, they bend down the bars of the iron structure that crop out the concrete, bind piano chords to them, stretch the strings down to the bodom base of the construct and connect guitar amplifiers to the set up. The Berlin Wall is ready to be played as a harp. Günter Schickert's Mauerharfe are executed between August and October 1990, resulting into three long field recordings.
