I did some investigating on the trailer and found out on the creator's home page (which is in russian) a link to NewTone which happens to be a russian band but also had a english version of their site. thank god. Its them who made the music for Collapse and including the trailer music. They used to be called Axess Denied.

now i laugh at you feeble mortal who wouldnt want to share the bands name for NOW I WILL PIRATE ALL THEIR SONGS ON P2P MUHHAHAHA! just because u didnt want me to ;)
