This is so true. I'm not comparing the musicals, I mean their style, just the same as you'd compare Prokofiev and Rachmaninoff, it's just which one you enjoy best. I think some of Andrew's musicals have great plots/stories, I'm just not crazy about the music :P
I personally don't like ALW at all...I mean do we need the word Masquerade 2000 times in one song?...My vote is for Sondheim. He can brilliantly weave 4, 5, 6... parts together, each different but work perfectly together...his themes are memorable, surprising, non-cliche...and he uses more than I, IV, V, I, by far. ;) Whatcher think? ;)
(In no order)
Tchaikovsky 6
Sibelius 2
Brahms 2
Mahler 6
Tchaikovsky 2
I also like Rouse 1, the other Tchaikvosky and Mahler symphonies, and Sibelius 5 :)
