Back when CD burning came in, I would often make up mixtapes complete with liner notes to give as gifts. Then one day I thought to make up a package. The music consisted of Strauss’ Death and Transfiguration and the Strauss song At Twilight, which references it in a closing passage. Then I added to the package an excellent discussion of the main work by Robert Greenberg, available from The Teaching Company.
The liner notes are below, followed by YouTubes of the music, though listening on a real sound system is preferable. I’d like to include the Greenberg lecture, and if I can lay my hands on it, I will post.
Death and Transfiguration (but listen on a sound system)
Ditto for At Twilight
