trees as co-authors of audible constructions

double glass pane sensor

A & B: importing was accomplished using taped and realtime Shure 635 microphones and Shadow sensors. Both amplified local and distant ambience from adjacent contexts using these inputs. Outputs could be directed to either (A) or (B). Additionally, UTC/GMT syncs allowed for the playing back at different dates/times. To accomplish these sound-in-sound transfers a four track Sony cassette and a TEAC reel-to-reel recorder were used to convey all soundings of a woods edge and aspects of an adjacent meadow. Realtime tests using the four mic amplifications required on-the-fly monitoring to lessen any g back through one or both layers.

"Ground truth refers to information that is collected "on location". In remote sensing, this is especially important in order to relate image data to real features and materials on the ground."

focusing on Sensor * above

initially, the concentricly placed sensors in my drawing were to be 1-heat, 2- strain, 4- vibrations, with the four shown here. In 3- I was questioning whether there should be a pH reading element added?, and *5-called for outputing from a triaxial accelerometer, with the analog results having been muxed and demuxed for sonic/sonographic soundings and display.

This was my entry in a Chicago gallery for the 1978 show titled "Mayor Daley's Tomb." It was curated by Jerry Saltz- current writer for NYMagazine. Earlier, at the time I was a visiting Artist at the University of Colorado-Boulder, it was possible for me to the visit The Tree-Ring Research Lab , University of Arizona, Tucson, US. I met and talked briefly with a grad student. Conceptually, I put forth my idea as to how I would like to track a trees growth rings using a modulated laser. And immediatelty l mentioned the pickup cartridge analogy of playing back a vinyl long-playing record; quickly adding that if it were possible, I'd appreciate hearing a cassette recording of such and gave my Iowa address. Our session was abrubtly ended and the student moved on to a scheduled seminar. No such recording or any followup occurred and the embedded cassettte-above- was to have had modulated laser tree ring recordings. The cassette does have actual recordings from two of R.J.Daley's speeches; an excerpt from his welcome to delegates of the Republican convention in Chicago's Union Stock Yards...": we welcome you to this great city in 1860...", and from a 1956 recording I made from WMAQ AM radio in Chicago while still in the Army (Ft. Belvoir Virginia): "...I will bring cilture to Chicago.." Notwithstanding the 1960s riots, and in fairness to the mayor, a Picasso scupture was erected within Daley Plaza in 1967. I was an undergraduate in the Art Institute's Schools and stood atop metal waste bin to see the work and to hear Seiji Ozawa conducting "An American in Paris."

Sketch Demodulated analog Metrologic laser relayed perturbances to the passed around laser beams caused by insects, earth rumbles, rain and birds- while simultaneously being received by a Metrologic radiometer and throughputing monophonic analog output soundings.

Helium filled aluminum mylar balloons, LAYERS ALOFT (Updated Vee projects of 1970-72)

each balloon monitored an area of approximately 2 square of space

26 FM radio "channels" were needed to make ascent and descent recordings and for playing back

like any balloon lift off, cool still nights are the best for this project

Modes: recording - to FMradio/listener&recorder

The single balloon carried a Velcroed soft solar array, 1 Watt styrofoam speaker, noise cancelling stereo mike, 2 Watt amplifier chip, and FM transmitter/receiver inputs and outputs were a part of the kite-nylon guying cable system. The outer covering required a soft edge to effectively minimize mechanical vibrations from being picked up via the mike line.

playback - per-balloon syncronism was not possible during rise or descent; however, I imagine a time shifting occuring upwind, and the technology for compensating-synchronizing was not available.

Preliminary Proposal for PS1, NY, 1978

Post competition words: Dennis Oppenheim later told me when we met at his show in Minneapolis that he thought such a project could not be feasable and executed.
