I really recommend the following. Before you're going to hear a piece, any piece, for the first time, don't do anything. Just go an hour early and read the program notes. Then you have some idea about how long it is, the instrumentation, what the idea of it is, the pure general shell. Then, when the piece is played, don't fight with it. Listen to it. And if you find anything that fascinates you, then here's the important thing: Go hear it again, soon.  -   James Levine     Quotes
