Klarafestival 2018 is a tribute to imagination, to inspiration and to the human creative capacity. Alles wieder gut, a quote from a song by Gustav Mahler, expresses the longing for a better world. Rather than a confirmation, Alles wieder gut is a call, an appeal: dare to dream, dare to long, dare to start working on a better world! The visionary composers on the Klarafestival 2018 programme like Beethoven, Mahler and Stockhausen heeded this call for optimism like no other.
