This track fits your description very well: Perplexa Mortis
The entirety of this sound fragment was made using various modern synthesizer-layers. Effects like distortion, reverbs and delays are used as well in a varying manner. The atmosphere constantly shifts from calm to unrest to reflect various feelings/emotions. The track begins off calm and ends at a climax.
This track is about the different feelings we have while thinking about life and death; about the paradoxal feelings and mystery we experience when confronted with or thinking about it. On one side it is intense and sad, while on the other hand, in a poetic-way, it also brings beauty. The valueable memories we have to cherish of our loved ones. It fuels positive things like passion, romance and hope in our lives. It makes you want to make the best out of every day, it enables you to dream. While life and death are two extremely different things, in reality they’re thightly interwoven in our daily behaviour. This song is about that; the twofold thinking, the various emotions involved (from sadness, to calmth, to bitterness to anger, ever alternating). The song starts off peacefuly, bringing a new life. Have a listen to decide for yourself how it ends.
