Worker's Union by Louis Andriessen performed by Bent Frequency

Workers Union was originally written for the orchestra De Volharding (Perseverance), in which I myself figured as a pianist at that time.
This piece is a combination of individual freedom and severe discipline: its rhythm is exactly fixed; the pitch, on the other hand, is indicated only approximately, on a single-lined stave.
It is difficult to play in an ensemble and to remain in step, sort of thing like organizing and carrying on political action.
-Louis Andriessen
