Beginning in the 1960s, Keith Sonnier was one of a few artists experimenting with neon tubing as a sculptural medium. His pursuit was part of a larger interest in using everyday and industrial materials, foregoing the illusory space of painting in favor of a more literal and direct artistic approach. The hard geometry and brightly illuminated lines here exhibit Sonnier’s fascination with the relationship between the viewer’s body and the work as a drawing in space, as well as the psychological impact of color and light.
