"... [Another] very beautiful experience was the concert of ensemble Pentagonale. They had a long program with a very complicated polyphonical repertoire from the late Middle Ages. It was a period in the music history when the compositional technique tended to go in this certain kind of rationality, in a peculiar mathematical extremeness. Most inspiring about this concert was the way, how natural was the experience of beauty that those musicians were able to create from this music, that is performed quite rarely. You cannot find much recordings of the frantically complicated music of Ars Subtilior and of the late Trecento composers (for example Johannes Ciconia, Matteo da Perugia). But the musicians of Ensemble Pentagonale performed those almost madly complicated rhytms in such a way, that the concert felt like a simple very emotional experience of beauty. This was a very rare experience."
