That reasoning would make Rachmaninov, Schoenberg, Stravinsky and Bartok American composers.
...and you flammed Jonathan Powell. He is a great pianist and from what I have read a very fine and unpretentious person. If I was you I would apologize and buy all his records. 
Hmm. Where to begin. If you take what I said as to mean that anyone who has ever composed in America is an American composer, by that reasoning I could just as easily make the connection that the point of YOUR post is that you like Keebler cookies more than Chips Ahoy. Now you may ask, "where in the world would you get that from my post?", but I feel I would be justified in asking how in the world you misunderstood my post to such an equally flagrant extent.
https://www.google.com/search?hl=en&lr=&q=define%3AflammedFlammed? I don't believe I have ever flammed before in my life. I have FLAMED, and possibly flambéed, but surely not flammed. I have NOT, however, flamed Jonathan Powell, or flambéed him for that matter. I would ask you to direct me to what exactly you classify as either. I only ever remember discussing his pianistic technique in comparison to that of Ian Pace's; if I said that my dog does not have the technique that Ian Pace has, I'm sure he wouldn't be offended. It would not particularly surprise me if Jonathan Powell is not offended either. Oh, and just to avoid it, because I'm sure one of the drama queens will make an issue of it, no I am not comparing Powell to a dog. And no, that does not mean I am saying "there is no comparison between Jonathan Powell and my dog because surely my dog is just infinitely superior."
@ mephisto: Am I "of course" wrong? Please, give me a name of a dated, publicated (or assuredly real) piece by Ornstein that was written pre-1907, the date of his emigration. I'm looking at the site Ornstein's son has made in homage to Leo, and I don't see one. Maybe I'm just missing it?
