Jamming jagged lines

June 17, 2009

Picture 4

Over at True/Slant Marc Herman breaks down some of the techniques involved in large-scale signal-blocking, as is the case all over Iran right now. “Jamming” is just one of them; the number of communications channels available today ensures that any entity attempting to abort unsanctioned communications has to throw the kitchen sink at the variegated sources. This piece is a good primer to often overlooked nuts + bolts comm basics for our amped age. It also makes me wonder to what extent these transmittal/reception disruptions are spilling over national borders, as Marc mentions.

As a brief and unrelated aside, how long have electronic signals been depictedfranklin_experiment2 as jagged lines, as in the illo in the T/S post (from a training manual resource)? Did the very first broadcasting proposals employ this imaging of the invisible? Did the graphic serration derive from invisible but measurable waves, such as sound? Or could they have tapped an older graphic convention: the visualization of lightning. From late 17th-century meteorological tracts (bottom image in the link) to depictions of Ben Franklin’s electricity experiments, the jagged line has long been the trope. And of course older yet (petroglyphs don’t count, everything is up for interpretive grabs), but how far back?

Subotnick on Bleecker Street

May 26, 2009

subotnick1

These great stills from an educational filmstrip show a mod Morton Subotnick in his Bleecker Street studio, most likely in the early 1970s. The analog synth apparatus here is the Buchla Modular Electronic Music System 100 series, which Don Buchla constructed from a spec by Subotnick and Ramon Sender. Subotnick resurfaced in my consciousness recently after attending the 45th Anniversary of Terry Riley’s In C (mentioned here earlier). Subotnick joined the 60+ musicians onstage on clarinet, which he played professionally prior to his career as a pioneering electronic music composer and musician. Subotnick is cofounder of the San Francisco Tape Music Center, a crucible of early electronic music whose influence on contemporary music is impossible to quantify. Its members included Subotnick, Sender, Pauline Oliveros, Tony Martin, and William Maginnis. (In an amusing twist, the former site of the SFTMC at 321 Divisadero is now the yoga studio in which my wife practiced).

The Buchla is what you hear on Subotnick’s early Nonesuch releases Silver Apples of the Moon (1967) and The Wild Bull (1968). Obviously technology and compositional techniques now far supersede these recordings, but what makes these listening experiences so incredible is still the sense of true novelty—these machines making these sounds for the first time. Today it may seem shambling, squawky, and warty, but this uncanny music charted entirely new terrain.

The history of the Tape Music Center is covered in this amazing book from UC Press, The San Francisco Tape Music Center: 1960s Counterculture and the Avant-Garde, with essays by and interviews with the Center’s founders as well as collaborators and contemporaries Terry Riley, Stewart Brand, Ann Halprin, and Stuart Dempster. My old friend Tom Welsh contributed his own independent research to the book and assembled the incredibly detailed chronology.

This passage by Subotnick in the book gives a glimpse of how blazingly fast electronic music developed in the late 1960s, and how prescient his vision was:

. . . I was in New York for a performance and made an appointment with the Rockefeller Foundation. . . . Since they had helped fund the Columbia-Princeton studio, I presented our dream. We would like the funding to work with electronics and sound in San Francisco. Soon people would be able to create with sound in their living rooms. We had developed a notion, not of an electronic organ, but of a sound easel that was closer to an analog computer, with which people could create with sound the same way they had always been able to create with paint and paper. With $500 for parts and a little more for some other equipment, we could create a facility centered around this idea.
The response of the Rockefeller Foundation was that, though it appreciated what we were trying to do, its view was that there would never be enough interest in this kind of thing to warrant a second studio in the United States. . . .

Subotnick moved to New York in 1966 and became artist-in-residence at the Tisch School of the Arts at NYU (who granted him enough money for the Buchla). Here his musical experimentation flourished.

By the end of 1967, two years after I left San Francisco and the Tape Music center was transferred to Mills College, I was living in a world quite different from the one I had inhabited a few years earlier, in which it had been supposed that there would “be so little interest that it would be cheaper to fly people to New York from all over the world than to build a second studio.”

Control

March 25, 2009

Condensed meditations on the control panel as a pervasive technological sublime:

The control panel was an invention of the industrial age, a manual interface consolidated into a conscribed area within easy reach of a single operator. Industrial machines would eventually yield to nonkinetic information machines. Even as these technologies became more quotidian, the idea of a priestly technological class solidified: control panels were operated by specialized men, technicians.

Grouped control panels aggregate to form control arrays, the ultimate realizations of which include military command hubs, nuclear reactor control rooms, and of course space flight centers: Mission Control.

This profusion of technological interface has long exercised a strong hold on the popular consciousness through science fiction and fantasy films. The proverbial figure behind the curtain of The Wizard of Oz was a puppetmaster of reality operating a panel-controlled illusion.

ozMuch later, an iconic distillation of control tech is found in the breastplate and belt of Darth Vader, a malevolent superbeing whose human distance from technology is collapsed; he wears the interface of his own hybrid mechanical identity.

Even as the specialist implication of control panels persisted, electronic appliances and lifestyle accoutrements increasingly found their way into the domestic sphere. The key entertainment and lifestyle components of the 1980s—the entertainment a/v system and kitchen gadgets—brought the control panel ethic and aesthetic literally into the hands of the middle-class consumer. Overdriven remote controls are rhetorical technologies; only half of the buttons, if that many, are functionally known to the user.

The demise of the Cold War resulted in a glut of technological detritus, and a new subculture of tech fetishists flock to the control panel aesthetic. Flickr has an active Control Panel group where members upload pictures of panels found in diverse sources, from eBay items, vintage stereo components, aviation boneyards, medical flotsam, and even detached pieces of nuclear missile launch panels. The ultimate aestheticization of the control panel may be found in the work of photographer Mark Richards, whose ode to the tech sublime is found in the book Core Memory: A Visual Survey of Vintage Computers (disclosure: I edited this book).

The final frontier may be the hard, masculine, and technical control panel aesthetic coming around to a softer and ultimately ironic manifestation: craft. Knitted, crocheted, and otherwise woven representations of the control panel are part of the vast DIY movement. Plush iPhones and soft synthesizers are indicators that the angular control interface responds to a human need for suave tactile sensitivity. The control panel of tomorrow may yield to a more physically and psychologically supple interface.
