Hi Joost, bravo !
You've successfully captured the magic & improvisatory spirit of Mozart.
I can only imagine how he might feel to see his music continue to endure 230+ years later, and performed on an arranger keyboard no less.
I bet he would not only be impressed by your performance but even more amazed by our 21st Century music technology.

My only gripe: cutting off your head in your videos looks cold & impersonal. The guillotine is outmoded.
btw: Nice to hear from you & speak with you on Skype yesterday.
