I thought I had deja vu here, and indeed I had. How many times have you posted this about Ives Dave ? Not that he isn't worth repeating I suppose. I can only post what I said in replying seven years ago.
As I implied in my response to this on Pianoworld, your videos on anything are always worth my while downloading and watching slowly in detail on the television. I have recordings of much of Ives, and was attracted to his music over forty years ago, especially the first piano sonata. I don't listen to him much now, but I don't listen to much of anybody so the observation is academic.
For me the big lesson of Ives, his life and music, is that we should all be ourselves, and only ourselves, and have the courage to create the sounds we enjoy regardless of fame, money, ought tos, shoulds or social consequences. The impression I get is that he created his music because it was the sort of music he enjoyed; he didn't write it out of homage to famous precursors or in consequence to fashionable intellectual speculations and theories, and certainly not to appear iconoclastic. He just played the sounds he loved and bugger what people thought. I like that. I think it shows in his music and I think it is the way we should all create.
I wouldn't have got on with Ives the man, his jingoistic philosophy and such repel me, even Elgar came to loathe what his Pomp and Circumstance represented, but once we get past a certain point in life the composer as a man is irrelevant. All that matters is the sound, and Ives created plenty of wonderful sound.
