The symphonic oeuvre of the Polish composer Grażyna Bacewicz has never before been recorded in its entirety 'from one source', so that the series beginning here represents a pioneering act. The Third Symphony for large symphony orchestra was written in early 1952 and the monumental and pathetic music shows a hitherto unknown face of the composer. One of its characteristics is the use of large instrumental blocks, although fragments also appear that hint at the lighter expressivity of the neoclassical tradition. It is a masterfully constructed work and the overt formal schemes of the Classical period are complemented by the subtle use of elements that were characteristic of music between the wars - in particular the timbres of the French tradition. Nevertheless, this work is not about setting new accents. The same applies to the Fourth Symphony. The orchestra of this work from 1953 is larger than in the previous symphony - among other things, English horn, E-flat and bass clarinet, contrabassoon and harp are now also called for. In both works, the composer achieved an excellent balance between the music of the past (form referring to tradition) and new sources of inspiration (folklore) as well as a new approach to traditional elements (rhythm). As a result, she managed to reconcile the autonomous, artistic qualities of her music with the expectations of the cultural policy of the time. We are very happy to have found congenial interpreters for this project, which sets new standards in the WDR Symphony Orchestra and the Polish conductor Lukasz Borowicz.
