Yes, "Summer haze" by Vanessa Mae
It's starts out slow and quiet, birds chirping, then to a little dramtic violin, then it keeps going on is rhapsody, and eventually the tempo picks up. Were still in sad mode, then its even more dramtic, then more, and then the big finally, with a highest pichted sound you would ever hear on the violin, and you hear the soft sound of an exposion ending the song.
I thought this might make a good vid for: Gundam Wing Endless Waltz. You could start out with the quiet Heero scenario, then switch to that girl, and all those happenings, then it goes to battle, then the final blow.
Sorry had to get that idea out...
