Create an Animation to a song

I require a unique and visually stunning video animation to be created for the following song: [login to view URL] The screen displaying the video content is 5.4 metres (18 feet) long and 90cms (3 feet) tall. The more creative and synced to the music the better. I want you to let the music guide you on what to create, the animation should be a perfect fit for the music. Preferably dark colours. I would encourage the use of depth and illusions. 3d if possible as the video is projection mapped onto a surface of the above dimensions. Something romantic perhaps? Something remarkable and visually stunning to look at that perfectly compliments the song.
