Viennese orchestral playing is a byword for excellence, rooted in generations of tradition. But under its distinguished (and adventurous) American Music Director Marin Alsop, the Vienna Radio Symphony Orchestra takes that tradition as a starting point to look outwards – to explore. Bartók’s bloodcurdling ballet suite prepares the way for Prokofiev’s Third Piano Concerto: energising, unsentimental brilliance, brought to life by former BBC Radio 3 New Generation Artist Benjamin Grosvenor. And then, two very different facets of the Central European tradition: the windswept drama and dancing Bohemian melodies of Dvořák’s magnificent Seventh Symphony, and the UK premiere of Heliosis – written specially for Alsop and the Vienna RSO by a young Viennese composer with a flair for drama.
