Poster printed on heavy stock board published in conjunction with a series of concerts performed at the Pasadena Art Museum, January, 28 - 31, 1968. Presentation included "Ornamental Lightyears Tracery."
"The projections form part of a series of light works designed for live performance on three or more slide projectors. The series contains numerous black and white negative and positive photographs of modular sections of several closely related designs. Each slide mount holds a photograph and a combination of colored gels. These design and color elements are combined into interlocking groups whose sequence, duration of appearance, and manipulation within the parameters made available by the functions of the machines are determined during the actual performance.
The symmetry of the designs and the repetitiveness of the patterns concerns centering and concentration. Movement is deliberate and takes place slowly in time. Performance usually accompanies La Monte's music, and the changes reflect the mood and flow of the sound. This series was first performed at the Pasadena Art Museum, January 28-31, 1968 as part of 'Map of U9's Dream The Two Systems of Eleven Sets of Galactic Intervals Ornamental Lightyears Tracery.'"—from press release for "SOUND AND LIGHT : LA MONTE YOUNG AND MARIAN ZAZEELA," The Museum of Modern Art, New York, December 30, 1968.
