Azaria, I also am a classical music lover; it's one of many musical loves, genres. Moldau is a favorite of mine, too. I love classical, and I love blues, and I love rock, and I love metal; other genres as well--the universal criterion being that it must be written and played with skill and spirit.
I have a present for you. I'll bet you haven't heard The Moldau done like this. Tell me what you think. This is an mp3, a little over 4 meg in size.
The Moldau
Gopher, I'm a Grieg fan, too. I talked the other two members of our band into doing a rock version of Hall of the Mountain King (as rendered by Wolf Hoffman, the same guy who's doing The Moldau, above). And sometimes I have gotten up in the morning and put on Morning Mood, by Grieg, to start my day off right.
Here's a link you might enjoy. Exposition on Moldau (which is a river that runs by Prague).
