As a Mozart fanatic, Father Bach is the only composer IMHO who even approaches Wolfgang's genius. He was a great influence on young Mozart, and with VERY good reason. Happy birthday Mr. Bach!
That is very arguable. While Mozart was gifted, his talent was also immature. Young Mozart has many of the characteristics of young Bach, which while quite good became significantly more refined with age.
IMO, Mozart is over-rated as his body of work currently stands. I think he would have been a spectacularly good composer had he lived another decade or so but we'll never know. Bach, on the other hand, was a true seasoned master of his craft with skill and judgement that few great musicians in history ever had. A statement that Mozart was better at this craft is mostly speculation; when it comes down to the actual works, Bach was the better man.
What about Beethoven, who wrote his most incredible music after going deaf?
I prefer Ludwig Van
