Prof. Rolf-Dieter Arens opened the 23rd SommerMusikAkademie Schloss Hundisburg on Saturday with a virtuoso and devotional piano recital. The opening of the academy was at the same time a farewell recital: The founder of the SMA hands over the artistic direction to the sole care of conductor Johannes Klumpp - with the promise to be infected by the festival fever as a guest.
