Maybe you recognize it, altough it is a different version, but still as good:

 Currently highly experimental! 


Coelum - Aiden's Lament
 Currently highly experimental! 

ps: Some credit goes to Haloprov, as I didn't know Wikia allows to embed Youtube links and I found some examples at his profile.

ps2: If someone wants to listen a better quality version of it (without SFX and better overall fidelity), here it is: Coelum - Aiden's Lament on Soundcloud

ps3: No, I'm not making ads for no one, I just liked this song and wanted to share it.
