Maybe he was a dissident, but his music is still boring to me. Or maybe his predecessors were just so boring that he was the first step away? I usually don't understand from his music why he is celebrated. Is it that he is just historically important? Like the discovery of logarithmic tuning of sqrt_12(2)? It could also be that I am just moved more by the romantic era. Mozart generally gets relegated lower in my list…
I wouldn't say that at all. It's versatile in a different way. Listen to some 20th century organ music - maybe start with Howells, Duruflé, Cochereau and explore from there.
