Hirsch Quadrat (which can also be written Hirsch²) was a short lived project of Christoph Heemann and his brother Andreas Heemann that was created in the late 1980’s when it appeared that H.N.A.S. was about to break up. Only two tracks were released: one for a Le Corbusier's Buildings / Die Zwei Arten Der Fettsucht (Zweite Art) with D.D.A.A. on the Belgian Electrip label; the other a track on the compilation LP Perpetual State Of Oracular Dream. Essentially these two pieces are the first and second parts of a suite. Additionally, a short fragment of raw material was also used on the Schimpfluch LP Stuhlgangblockade N!.
