Having trouble finding FLACs, even MP3, or even any real information about whats on it or what promo event it came out with.

Can't even find music on Youtube

What is this?

It just contains 1 orchestral track and a bunch of visual data:
Game Music :: The Legend of Zelda Twilight Princess Sound & Visual CD (Nintendo Dream) :: Album Information (http://www.squareenixmusic.com/albums/z/zeldatwilightsound.shtml)

I believe it's the first orchestra piece you hear when you startup the game.

Maybe this project interests you more: http://www.zreomusic.com/

It's a team of people who is about to create an orchestrated version of the soundtrack of The Legend of Zelda: Twilight Princess, funded by fans.
