"How does she do that?" This is a question that blind singer Gerlinde Sämann, who has already performed in the Konzerthaus as a member of the Balthasar Neumann Choir, is asked time and again. This concert will answer it with an experiment: In the dark, the audience can listen to the evening of works for soprano and harp and watch themselves as their hearing and other senses are heightened. Experience the concert as usual on chairs or sometimes on a beanbag, cushion or lying down (you are welcome to bring your own yoga mat or similar).
