I'm not confused at all. Charles Ives's music is shit, and the only reason he ended up being reknown in the first place was because he claimed to come up with a lot of Europe's most innovative 20th century techniques first. An examination of his sketches showed that he often altered the dates on his pieces, claiming that they were composed earlier than they actually was. Some guy named Schoenberg devised a new 12 tone system? Doo-dee-doo, I'll write a 12 tone piece, then date it a few years before he did it, I'm innovative!
Never trust an insurance salesman.

Ives is probably the only major 20th century composer that I have no respect for.

There is a CD availible called "Ives singing Ives," or maybe "Charles Ives Sings Charles Ives." Something like that. It is absolutely atrocious.
