The pianist Alexandra Sostmann is not only known for her polished Bach playing, but also for her concert and CD programmes that trace developments and cross-connections in music history. In her latest CD recording, she remains true to this approach as she spans the period from the Baroque to the present day, seeking to shed light on the concept of music as a medium between immanence and transcendence that can be found in almost every culture. It is above all the transformations and transitions reflected in the music that fascinate the pianist. But silence also plays an important role - as an integral part of music and as a cipher for that which cannot be expressed in words.
