There are just certain pieces of music that stay with you. They work their way under your skin. You live with them and, for better or worse, they become a part of you. There's a lot of music I love and I'm not trying to create a "desert island" list.
I bought John Adams' Naive and Sentimental Music when it was first released on CD in 2002. I bought it on a whim and was immediately taken with it. I had been enamored of Adams' music for quite some time and I'd been buying a lot of it for some time. I liked the piece a lot for a time but I don't think I really "got" it and more-or-less kind of shelved it, listening to it every once in a while.
Then - in 2006 I think - I bought the score. I've been reading it for over four years now and it's slowly revealing itself. Yes, it's a "desert island" piece but for me it's so much more than that. It's a piece that I could just crawl into and live inside for a while. I dare say that this piece might have changed my life. It never gets old, never grows tired. In a way it nurtures me. (It's a little disheartening to know that I'll probably never hear it in my hometown unless it's being played by a touring group.)
There are a handful of other pieces like this but Naive and Sentimental Music is probably the piece that means the most to me in this way.
What do you think? What pieces go beyond being "desert island pieces" for you? What works are a part of you?
