I find it sad that you have got past your LMus (which is no easy feat) and don't have vision yourself as to what repertoire you could explore. Have you merely played pieces you have been told to do you whole life? Surely you have explored music yourself and been drawn to particular works? I find it just random to ask people online what you should do, what is stopping you from exploring yourself? If you do that surely you can create a list yourself.
Hmm, kinda feels like the pianist is just in a hurry in that first recording, and that its natural tempo should be a bit slower. Does not seem to a be a suitable tempo for the harpsichord at any rate... me no likey
