Henri Pousseur and Pierre Bartholomée founded the Centre de Recherches musicales de Wallonie In 1970; it was renamed Centre Henri Pousseur in 2010. The Centre is the only artistic institution in Belgium that is completely dedicated to the development and performance of mixed music; the year 2020 marks the 50th anniversary of its unceasing efforts in the service of this particular field of musical creation.

The Centre has selected eight mixed compositions, each of which was developed in the Centre's studios in Liège by and with composers closely associated with the institution, from the Wallonia-Brussels Federation, from Flanders, and from other countries. This release not only highlights some of the most recent developments in mixed music, but also recalls the musical originality of Henri Pousseur, the Centre's founder: one of his most important mixed compositions was updated by the Centre on the occasion of the 10th anniversary of his death in 2019. We are sure that this well-filled release – it contains more than two hours of music – will be a fine testimonial to the special character of the Centre Henri Pousseur and to its close and lively collaborations with composers and performers.
