SOPHIA, Composer's Ensemble, Denise O'Neill and Ann Sandifur, is a recently formed ensemble although the members have worked together for several years. Sophia, then, is an experiment in artistic democracy depending on maximum cooperation and adaptation of the members while maintaining maximum individual freedom of expression and integrity, to composer and produce pieces within a complete environment as art.

Denise O'Neill's interest in new music is in the conception and rendering of sound as environment. She lectures on lighting design, composes, works on scenic designs or performs one of these functions at various concerts throughout the Bay Area.

Ann Sandifur's interest in art is to explore the behavior of consciousness and to communicate through compositions of consciousness the quality of this behavior, experiencing this exploration as a direction and as a perspective. Having received an undergraduate degree in music composition an an M.F.A. in electronic music, she is currently pursuing the Ph.D. in environmental design.
