The Konzerthaus Orchestra, conducted by Joana Mallwitz, kicks off the new season with the hypnotically intense “Bolero” by queer composer Maurice Ravel, combined with music by Beethoven, whom many also interpret as non-heterosexual (his First Symphony will be performed). There will also be music by a female composer: Anna Meredith's “Nautilus.” The concert will be streamed live to several open-air cinemas.
