i love mozart, esp. his requiem. I got to do some traveling in europe this summer, and go to salzberg and vienna (got a pic. of mozart's 1st violin, ... then got in trouble for taking said pic)... but yeah. Listening to his requiem in a huge gothic cathedral was... oooh my god. I am also a horn player, as are my parents, so I was raised on his horn concertos, which are nice.
I also highly enjoy holst's planets, the bach cello suites (esp. the prelude to the first), the lieutenant kije suite (can't remember who wrote it

)... i also enjoy me some rimsky-korsokov.
