The world, people changes incessantly… Technologies develop and cities absorb nature and all around them. And there will be a day when most of the human population will stay underground. The intro starts from mysterious and dark sounds which imitate the steps in an empty tunnel. The emotional, sad piano and alto melody create the feeling of something lost, hidden from your sight. This composition is an ideal pick for a futuristic fantasy film or documentary. Or simply, add this deeply romantic track to your playlist!
