Heinz & Franz was a home recording project by Heinz Havemeister and Frank Bretschneider. The recordings took place in 1987 and ’88 in the DIY studio “Sonnenklang” in Karl-Marx-Stadt (now Chemnitz), always at night. The mixing desk was self-built. 50 copies of the tape were released on Bretschneider’s label klangFarBe. Heinz Havemeister was a guitarist with the Bolschewistische Kurkapelle and co-editor of the art samizdat “LIANE”. Frank Bretschneider is considered an electronic pioneer of the GDR underground scene. He worked in a range of projects, including with the legendary band AG Geige. In 1995, Bretschneider co-founded the Rastermusic label, which cooperated with musician Carsten Nicolai’s noton label. Both labels merged in 1999 to form Raster-Noton, an influential label for experimental music in Germany. Bretschneider’s work has appeared on labels such as Mille Plateaux, Quatermass or Staalplaat.
