The Music

Ok this has been driving me nuts... dose anyone know where i can dowload the jazz song that plays during the episodes? i have been looking forever... well... more like 2 hours but still. any help would be awesome. THANKS!

That song is called Brick Ballades and is on the second Big O OST. You can buy the soundtrack from CD Japan or other online stores (be sure to watch out for bootlegs by reading the guide, though).
