“I have no doubt he was a great teacher….” What exactly are you implying; that those who can’t do, teach? Is that what you’re saying?
Please get your priorities straight, and make sure you let Bach back into your life, and if you now feel Liszt is worth listening to/for hours, yet you ‘can’t stand Bach’s music for too long’, it is only because you’ve strayed from the narrow path, where all the good stuff exists, and followed the wrong crowd into a wide & shallow romantic mirage that might entertain, yet does not enlighten. I have seen him, Bach; and yes, I’ve also seen his son, Beethoven!
