He is no Mozart. He is not even close to a Bach.
I know Mozart's work fairly well but I am no expert. The scene in Amedeus where F. Murray Abraham ( won an Academy Aware for it) curses God for Mozart was pretty accurate. Abraham played Mozart contemporary Salierni (sp?). He never was as good as Mozart and the film portrayed Salierni as destroying Mozart. It is somewhat fictional but he curses God for putting Mozart on earth. Mozart could pour out beautiful music as fast as he could notated it
There will never be another Mozart. Bach was a another giant but he lived much longer than Mozart.
I doubt he was. I know that when I really listen to Mozart I am taken out of it. Which is very good.
