Keith Sonnier was part of a group of artists who challenged preconceived notions of sculpture in the late 1960s by experimenting with industrial and ephemeral materials. In Sonnier’s case, materials ranged from latex and satin, to found objects, transmitters and video. In 1968, the artist began creating wall sculptures using incandescent light and sheer fabric. Frustrated by the standardized forms of incandescent light, he started experimenting with neon. Using copper tubing as a template, Sonnier began sketching lines, arches and curves ultimately realized in glass tubing enclosed neon. The linear quality of neon allowed Sonnier to draw in space with light and color while colored light interacted with the surrounding architecture.

“I think everyone at some point comes up against a wall. Curiously, though, if you continue working, you might readdress that idea from another direction. If you didn’t try something, you’d never have anything; if you didn’t make an attempt to make the work, it wouldn’t exist. There have been times when I could not work, and I would just go and sit down in the studio and wait to see what might happen. You can’t always just go and take an exotic trip and come back and make something.”

“Sculpture, for me, provides that environmental discipline where you actually move in and around it”.

“This is New York. You gotta work from upstairs to downstairs! You gotta work both ends of the street to have a career. Because it’s not just fabricating an artwork. Your works have to go out into the world; they have to go to market. This art on the hoof has to be moved; it’s got to go to the slaughterhouse at some point.”

“A lot of artists are good cooks as I’m too, but coming from a culture that was very concerned with food, I was very interested in that from the start. If you’re interested in food, you’re interested in lots of different aspects of culture. And it’s like being interested in the music from a certain area, or writing, or whatever–food is part of that, too.”
