TeleSuonohologram (stitching sound & video image), 1984
While an undergrad at SAIC in Chicago I remember visitors to art classes: Robert Rauschenberg's sound-producing and sound-activated works in the 1960s. I paused daily during frequent walks through Gunsaulus Hall to catch my Michigan Avenue CTA westbound bus. The gallery space was not a usually crowded-except on opening afternoons- and I zoomed in on the R. R. island of found (v.tr.)soundable-objects. I listened to invasive reverbs from floor bound metal objects being reflected from cloth-covered walls. Run-away-radio dials. Deep-throat sounds vibrated from a wheeled tuba which, for this gallery over the Illinois Central commuter tracks, was surrounded by mute glass-framed glissening images looking on and aimed like focused solar panels upon this "sculpturalinstallation entitled Oracle." Interactivities were possible and anyone could scan the AM and FM radio frequencies. Not the first time nor the last time sound entered the usually hushed visual gallery. The human made artifacts which Rauschenberg selected and assembled were very much at home in the steel, brick and hand carved stone structure. My own 1984 telesuonohologram soundsculpture http://www.d.umn.edu/~lbrush/lbarchivesf4.html also used human made materials and was constructed to be a realtime "Soundmirror" of the environment (not at all for recording as in http://www.vidipax.com/museum/msm16.html but rather, in realtime uses). http://www.d.umn.edu/~lbrush/lbarchivesf4.html In the actual set up position on the grass, the parabola had 200 front surface mirrors and was aimed at an opposite round disk which was also covered with 200 mirrors. ((DETAIL: http://www.d.umn.edu/~lbrush/teleSUONOhologram.jpg))
The teleSuonohologram concept was an audio and video recording system prototype which momentarily merged and focused both sources and produce temporal experiences.The video monitor and amplified sound were contained within the focal positions of the parabola. As an ongoing experiential moment in time, the ephemeral mirage/image/sound was not technically "recordable." A mirage was apt and it levitated, holographic-like http://en.wikipedia.org/wiki/Holography , for as long as the viewer remained cross-eyed. During faculty showing of the work, it had to be cut down for it to be seen and heard.
I also heard a Robert Smithson http://www.robertsmithson.com concept which was, for me, THE aside from his '68 chat with students in SAIC'S Fullerton Hall: "...artists should have their own satellite..." Thanks to University of Minnesota Graduate School and National USA Art Endowment grants I was able to conceive, rent and executed a Teleconstructs series of two-way interactive Westar IV satellite projects and the first was Hudson River Museum http://www.hrm.org Teleconstructs Spacework I http://www.d.umn.edu/~lbrush/lbarchivesf4.html#anchor149487. Eventually my concentration focused on web networking interactivity potentials. In January China shot down an old weather satellite with a ground-based ballistic missile http://www.theaustralian.news.com.au/story/0,20867,21088246-2703,00.html.

at SAIC: now a grad teaching assistant of my own sound-centered class, Audible Constructs http://www.d.umn.edu/~lbrush/lbarchivesb1.html. Sound collecting used 1/4 and 3/4 inch tape, was sensor-sourced "field recordings" and also monitorings of the Hexagram- a group project installation on SAIC's roof. North of and some distance from the Chicago's Loop on a quiet Montrose Harbor http://www.catfleet21.org/CruisingGrounds/montrose.htm mound the class were able to overhear and experientially listened to the unique and rather quiet soundings. These were from randomly-proportioned atmospheric elevations using helium filled balloons and via FM 2-way, these transmissions were recorded to/by FM/cassettes http://www.d.umn.edu/~lbrush/lbarchivesb1.html#anchor270517, http://www.d.umn.edu/~lbrush/lbarchivesf2.html#anchor338757. Only sound/vibrational-targeting sensors were used. And though passing aircraft to and fro from O'Hare Airport gave us loud bonuses to deal with it was from turbulent gusts that contorted the rubber surfaces. Surface-attached strain gauges http://en.wikipedia.org/wiki/Strain_gauge persisted long after the northbound outerdrive traffic had faded out nearing 500 feet. A variety of transducers replaced the DJ-air microphone (get what you hear and playback what you heard with an ambient bonus). Students went on attaching sensors from berberry bushes, apartment plumbing and couches to FM wireless mics in some of the widest cracks on Michigan avenue. Conceptually on through post MFA days my unfolding processes have continued to be sustainably economical. I've hovered and drifted in Hexagrams within Greenland Highs and Icelandic Lows http://www.d.umn.edu/~lbrush/lbarchivesc.html pondering global's ground truth using Terrain Instruments, sounding tree "sculptures," terra firma's embossed terrain and Lake Superior ice floes.
Gloria DeFilipps Brush http://www.davidrumsey.com/amico/amico1364935-101218.html , sumarised pre and post 1973 Terrain Instruments http://www.d.umn.edu/~lbrush/terraininstruments.html "...Leif Brush describes his systems for creating and listening to and sometimes modifying the sounds of hidden, unheard natural events. In one of his outdoor installations, galvanized and stainless steel wires strung between trees can be monitored. The large-scale site-specific pieces use special contact sensors or transducers, attached to wood or ribbons, to amplify microsound events. FM radio transmitters are used to carry preamplified vibrations of atmospheric phenomena acting upon man-made sources. In some cases sounds are presented as they are, in others sounds are manipulated electronically. Among the many installations, projects and his own writing are Giant Ivories http://www.d.umn.edu/~lbrush/lbarchivesb1.html#anchor624919 , YONY, SAIC Publication http://www.d.umn.edu/~lbrush/lbarchivesYONY.html Insect Broadcasting System http://www.d.umn.edu/~lbrush/lbarchivese.html#anchor85180 , Iowa Riverharps http://www.d.umn.edu/~lbrush/lbarchivesd.html#anchor313228, http://www.d.umn.edu/~lbrush/lbarchivesd.html, Chord Draft Monitor http://www.d.umn.edu/~lbrush/lbarchivese.html, Signal Discs http://www.d.umn.edu/~lbrush/lbarchivesf3.html, Meany Ice Floe http://www.d.umn.edu/~lbrush/lbarchivesf.html, Treeharps Network, Windribbon http://www.d.umn.edu/~lbrush/lbarchivesf1.html#anchor, TeleSuonoQuad http://www.d.umn.edu/~lbrush/lbarchivesf4.html#anchor141645 , TelesuonoHologram, TeleSuonovision http://www.d.umn.edu/~lbrush/lbarchivesTELESUONOVISION.html, Selfbroadcasting trees http://www.d.umn.edu/~lbrush/lbarchivesf1.html#anchor230306 Terraplane Chorographies http://rhizome.org/object.php?46948, and The Telephone Finally Earns Its Keep http://www.d.umn.edu/~lbrush/lbarchivesg3.html#anchor465118, Lake Baikal http://www.d.umn.edu/~lbrush/lbarchivesg3.html#anchor243564, At this time all concepts involve solar powered electronics and satellite transponders..."
