Hi.
After over 15 years i finally found this video (didn't knew the name of the song or how/where to look for it)
This is a classic animation that worked as music video of a orchestral song, the song name is "Valse Triste" (i think, since it seems to mean sad waltz.. so im stil not sure)
I have to say that I love this video, is amazing and very very touching, so now that i found it (on youtube) i like to share it with you (whoever may care)
Please check it, it totally worth it
