Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
During the 1960s and 1970s, light became the primary medium for a loosely affiliated group of artists working in Greater Los Angeles who were more intrigued by questions of perception than by the notion of crafting discrete objects.
...Often with modest means (a bolt of scrim, a sheet of glass, a bucket of resin, an open window) these artists engaged in a kind of aesthetic palate cleansing, shaking off the art-historical weight and heavy impasto of midcentury painting as it had been influentially practiced in New York and San Francisco.
This is not a catalogue because there is no list of works. The exhibition will comprise three spaces in which three artists will have made their art. At the moment of writing we are not sure exactly what they will do—and we cannot know how what they do will appear to us. Therefore we cannot attempt to help you perceive it. So this is also not truly an introduction to the art. It is not intended to be read until you have seen the exhibition.
In between these two extremes is a room with three constructions by Robert Irwin. These can be read as individual works of art but their function here is primarily that of creating a climate of fastidious ambiguity. Light turns into a new kind of material; new kinds of material are fused into light; a vaporous middle-world stands midway between total black (Bell) and total white (Wheeler)
