The concert season of the Ruhr Piano Festival 2020 has suffered heavily under the Corona pandemic shutdown – loosing more than 85% of all scheduled concerts. In the late June/July days some concerts had taken place, some were live recorded; some concert also had taken place in the early autumn 2020,before the entire new planning was cancelled as well for all 2020, like for so many other concerts and festivals. At least the few live recordings are showing an interesting picture of a list of unknown piano works of Beethoven. It is therefore for sure a rich source for collectors and connoisseurs.
