This piece is as result of the composers sonoristic pursuits. It is characterized by unusual performance forces (soprano with a microphone, brass group, expanded percussion section, one piano used by two pianists and strings, in total - as in the title, 67 musicians), the application of quasi - stereophonical effects and a tendency for reduction of musical means.
