A couple of days ago I watched a YouTube clip of Vierne's Impromptu, wonderfully played by Loriane Llorca on the Oloron organ...
Because many of my appointments have been cancelled (due to the Corona virus) I had a complete day off. I decided to spend it on recording the Impromptu on the Oloron set, so we can compare a recording of the real deal to the Hauptwerk version... I'm pretty sure I was able to figure out Loriane Llorca's registrations.
I hope you will enjoy this experiment!
