It's Senator Armstrong's theme song from Metal Gear Rising. Collective Consciousness is his song, not that other one. We'll get to that.
Not much to say on this one; fun song, but Excelsus isn't a fun boss. Armstrong in Sam's campaign is scary, but a better fight.
Original song composed by Jamie Christopherson, for Metal Gear Rising: Revengeance, by KONAMI and PlatinumGames
