Keeping with the theme of this issue, some of the more delicate permanent pieces in Scottsdale's collection include works of light and glass. Noteworthy are James Turrell's Knight Rise Skyscape in Will Bruder's Museum of Contemporary Art.

The temporary program runs the gamut.

FEATURED ARTIST: CHRISTOPHER JANNEY

Christopher Janney came to public art via architecture and music in the late 60's. We've always found sound sculptures to be a challenge, because they are not always intuitive in order to be heard as the artist intended. What impressed us about Janney is that he conceives of sound as a visual medium, often referring to it as color; he sometimes provides 'instructions' or 'riddles' to show the possibilities. Through a series of Soundstairs, he began to explore the boundaries between music, sculpture and architecture creating what he termed urban musical instruments for viewers to 'play'. The Sonic Forests are groves of 'speaker' trees activated by the motion of viewers. The resulting 'music' is site appropriate. These are overlaid with additional components that change over time: light, color, and sometimes steam.

Circling at the Dallas Fort Worth Airport is a '21st century' interactive three dimensional labyrinth created from a colored glass spiral along a terrazzo path that is meant to be evocative both of the planes circling overhead and the passengers themselves circling through four concentric rings. Here the sensors that trigger lights and loudspeakers are embedded in the floor along with a riddle etched in the terrazzo telling visitors which path to take. Another airport project, Light Waves: Atlanta develops the concept further creating a 'light ballet' featuring changing lights over panes of colored glass along a long corridor accompanied by a score of native Georgian environmental sounds.

Whistle Grove: The National Steamboat Monument juxtaposes high-tech smokstacks with an authentic riverboat paddle. Here viewers activate jets of steam and stories of riverboat captains, voices of mean loading ships, and music from a calliope as they pass through the towers.
