strauss's "also sprach zarathustra".
did you ever listen to the whole thing? it's an interesting piece. you'd think that strauss would simply develop the catchy "hook" of the song, as heard in kubrick's "2001: a space odyssey". but he barely touches back on it.
still, worth the listen by all means.
A true lover of nature does not despair now that his mistress has turned a colder cheek.
