In August 2003, Lampo invited Swedish artist CM von Hausswolff to do a project specific to Chicago. Intrepid traveler that he is, Hausswolff ascended to the top of the 100-story John Hancock Building and collected sounds from the open-air observation deck. While taking in the sights, he recorded building vibrations, passing breezes and overheard speech from tourists. Later, in his Stockholm studio, he added a series of feedback rotations to suggest crows (guardians or enemies?) encircling the conceptual tower. The result is this belching, super dense, low-end drone work. Hausswolff's new piece is his rumination on security and paranoia. What makes us safe? Is it better to dwell in a cave or in a skyscraper penthouse? Could be another lecture on sound and architecture. We hear a secret gastrointestinal message.
