An exciting journey through the time: Mozart played on a fortepiano, according to 19th Century performing style, with today sensitivity. Keiko Shichijo introduces us to Baron van Swieten's salon, where Mozart used to play the piano in the early 80s. In this salon Mozart got to know in depth the music of Bach and Haendel. Keiko constructs a clever programme of great masterpieces somehow related to these years and to the new influence Bach excerted on Mozart.
