First televised on KQED in April 1969. It was a highly effective synthesis of abstract visuals—chiefly Arlo Acton's spherical sculptures of glittering titanium—and a soundtrack on which Terry Riley played hypnotically repetitive music on a soprano saxophone together with the feedback from two tape machines. The Dilexi Series, originally broadcast over KQED in San Francisco in 1969 and 1970, represents one of the first efforts to present works created by artists specifically for television. The 12-part weekly series was conceived and funded by Jim Newman and the Dilexi Foundation and produced for KQED by John Coney.
