Kupka’s Piano tackles the pinnacle work of the French spectralist canon, Gerard Grisey’s monumental sextet Vortex Temporum. Taking a swirling figure from Ravel’s Daphnis and Chloé, Vortex pushes it to its limits, to its self-destruction, and then to its resurrection. To compliment the 40-minute masterpiece, the concert commences with Kupka percussionist Angus Wilson’s interpretation of Karlheinz Stockhausen’s popular yet elusive solo work, Zyklus.
