Originally, Workers' Union was written for the De Volharding Orchestra (whose name means "perseverance"), of which I myself was a pianist at the time.This work combines individual freedom and rigorous discipline: while its rhythm is very precisely imposed, its pitches, on the other hand, are noted only very roughly, on a single line staff.

It is difficult to perform this work while staying "in step", for the same reasons that it is difficult to organize and implement political action. And just like in political action, this work will be a success if and only if each of the performers plays with the awareness that their individual role is essential to the group. -Louis Andriessen

Quasar performed Workers' Union in January 2014 with the La Machine and Quatrix ensembles.
