Hey Bud, you might be on to something there! Rearden metal.....
Since we are not talking exclusively trumpet/art related books (sorry, with my first answer I was addressing that.....hence the heaviness of the list)
Lighter deep reading:
The Planets by Dava Sobel
Galileo's Daughter by Dava Sobel
The Prophet by Kahlil Gibran
MEG by Steve Alten (if you're into sharks and want to be scared to death)
The Devil Wears Prada by Lauren Weisberger (no, I didn't see the movie, but the book is a great read for NYers)
