Not meaning to be argumentative, but "J.S. Bach is better than all mentioned put together" is not just "one man's narrow minded opinion." There are a great many other composers who shared that same narrow-minded opinion, as do a fair number of other music lovers, myself included.
I was turned on to JSB by the smartest human I have known in my life, a music major and graduate of The University Of California at Riverside, known for it's excellent music department. He also loved Mozart and Beethoven, but put J.S. Bach on a pedestal above all others. Genius on his level comes along only once every few centuries.
