this gives me goose pimples every time i hear it. so dark, creepy and disturbing. fantastic piece of music though. it is by Mussorgsky and called 'Night on Bald Mountain'
The second movement of Grieg's piano concerto has always had a special place in my heart. It's such a beautiful piece. I'm kinda picky about the performance though Couldn't find my favorite, but here's a good one.
Vivaldi's violin concerto in A minor. My dad introduced me to this piece when I was little. I must've listened to it many hundreds of times now.
I can't put into words how much I love this piece. It touches me so deeply. It's almost become "part of me", if that makes sense. I often find myself humming or whistling the main theme, without even realising it. That's how deeply it's embedded in my consciousness.
It's difficult to find a good recording of it - it's often played too fast. Here's a reasonable recording:
