David, it's true that these are notably great performers and composers. I was thinking more of today's craft when I wrote that- the repertoire is so large and challenging now that it'd be very hard to accomplish both. And it's hard to get the sponsorship of a king or queen now Anyway, you're right, that was an inaccurate generalization on my part.
Michael, I agree and I think different for its own sake isn't terribly satisfying. It does occasionally lead to something interesting though. I have seen a lot of very interesting mistakes, even.
Anyway, I was attempting to promote balance.
