The Illustrious Theater Orchestra were a chamber group founded in 1989 and based out of Cal State Fullerton. Led by saxophonist and keyboard player Shane W. Cadman, they consisted of keyboard player Paul Greenhaw, cellist Christine Dietrich, baritone saxophonist John P. Hoover, and clarinetist Scott McIntosh. Unlike any other classical chamber ensemble of their time, the Illustrious Theater Orchestra insisted on playing their own compositions, which were informed to a small extent by minimalism and were unvaryingly tonal, though not "new agey," and they did not venture into jazz-styled territory or indulge in improvisation.
