An
approximately three year old American elm sapling was removed
from our front lawn and allowed to dry before being subjected
to a mildly vibrating miniature motor. It was attached to its
base with a rubber cushion (for dampening). This specimen appeared
to me to be a miniature of its full and mature growth. In effect,
I felt that some vibrations would generally be in the analog frequency
ranges of a mature tree. I plan on obtaining aural and visual
signatures in future projects.

Press-Citizen, Page 3A The sound of raindrops (by Leif Brush) in Iowa City, an infra-red photograph
of the sun transmitted from Pittsburgh (Willard Van
De Bogart) and "sequential
drawing" from Chicago (by Sonia
Sheridan) produced
this "composite joined image." The image was made by
transmitting the three sets of soignals, in conference
phone call, and picking
up a "composite image" on facsimilie machines located
in the three cities.
1970s analog facsimilie
Telecopier (fax) manufactured by 3M
by which the grey scale of an image was read and translated into
the audible range of frequencies-- from which imaging was created
by a stylusand carbon correspondingly scratching into an off-white
coated paper having a carbon base. ((These
needles gouged out a continuous grouve, tracking as in LP or 45rpm
recordings; however, the disc recording medium is plastic.))
A
cassete has played back line-scanned sounds-in audio range- into
the Facsimilie Telecopier: band 1 telephone talk, 2 rain drops,
3 telephone dial tone, 4 wind, 5 dial tone, 6 wind at higher volume,
7 sine wave. (In this B&W 8 x 11 inch sonogram a steel stylus
actually recorded a series of grooves into the carbon-coated paper.)
Bands
over time depicting sound-only from three telephone sources joined
in a AT&T landline conference call.)
The
recorder playback syncing of these shown Faxes was not possible
and resulted in imaging shifts. return

mixing
three analog-shited signals into the facsimilie (typical out-of-sync
results; however, LB's hand/wrist shows little distortion)
This
focusable parabola, using a scrapped camera tripod, was able to
position the dynamic microphone at the precise sounding position.
Recording challenges, in daytime and nightime included the skimming
slightly ove theplane of crickets, tops of prairie grasses, red
clover and wheat and corn stalk tassels.

(picts fr/Lake Michigan) Continuing from earlier directed AM
radio-transmitted Lake Michigan on- shore paintings, I've updated
the process to include altering human made objects. In Iowa I
also used the two-way radio to direct fast drying acrylic paints
to alter the appearance of a specific object on/in the landscape.
In Coralville I decided to alter the barns physical presence.
Descriptive tape recorded comments and reactions spoken by myself
prior to painting were played back and used to influence those
colors and forms. To be successful, the painting would have to
totally transform the barn-visually- and yet be re-fited into
the environment and remain a compatible "man made structure."
I departed acrylic painting media and did not get to cover the
roof and other walls. From this aborted experience, I could see
that I would be somewhat successful- were I to continue- and did
not finish. I had more pressing interests. Our only daughter,
Sanna was born. Gloria's teaching quests. Our one acre farm. The
challenges in my evolving soundwork constructions offered challenges
and all this was shared my U o I owa City, Fine Art classes.

Students on both
shores sail their canvas from the campus bridge above the Iowa
River, and some distance beyond, lands it in a nothward direction.
The Art/Art History Building is on this side and the student center
is on the opposite bank. At least 5 battery operated FM transmitters
worked to sense the available sounds on board the canvas and broadcast
them. Selecting from among the 88-108 MHz frequencies determined
what was available. A student was free to select by hand-tuning
any available frequency.

shrouded the parallel steel supporting beams.
This Terrain Instrument "sound
sculpture's"* initial design and concepts were lauded by
then University of Iowa President and the some members of departments
including computing, physics and engineering. Art unanimously
abstained. Though the river flowed closest to the liberal arts
school, they hosted only the approved Graduate College feasibility
study and other paperwork flows. Students who would have signed
up in advance could accompany their instructor and were both
assured privacy by using a retractable jute ladder. The then
developing Iowa City Center for the Arts staff were to have planned
events around an accompanying moored barge (shown above) would
have been tied up beneath the RiverHarps and nearby Clapp Auditorium
