The Uncertainty Principle is a journey into the mystical musical world of Russian composer Alexandre Danilevski, where music and instruments from the middle-ages to modern day meet and create an unexpectedly beautiful soundscape. On this recording, Danilvski's own ensemble Syntagma interprets two of his works for mixed ensemble and voice, while the Flanders Recorder Quartet plays his "Antiphones" and cellist Larissa Groeneveld presents "Revelation", a concerto for cello solo.
