Monster Holy-Grail Sound-Art / Sound-Sculpture / Live-Electronic / Drone Masterpiece by German Composer Hans Otte, one of two titles issued by the Kölnischer Kunstverein's in-house imprint - the other being the Nam June Paik / Takis "Duett Paik/Takis / Klangraum Takis" LP - featuring excerpts of a staging of the piece "On Earth" given there on June 13th, 1979. Bookended by a narrative / descriptive overlay spoken by Elisabeth Weber & Wilfried Grimpe, the piece quickly ascends into a whir of subtly animated electronic timbres, seemingly emanating from a series of flat black cubes laid out on the gallery floor. The result is that of a more tuned-in version of Roland Kayn's massed long-form works, heavily utilizing the space's gorgeous acoustic as a resonant filtering agent.
