Well it's one year to the day since the soundtrack for Assassins Creed II was released and it's been a long year if you've been waiting to hear more from Kyd's work on the series. I love what he does with a series. There is always such a great arc, a story that is told not only from song to song, but from game to game. We heard this in the Hitman series; each iteration not only built off the last but experimented with techniques, narrative perspectives and dynamics. The arc in Assassins Creed is much more subtle, much more nuanced. You go away understanding the feeling of the world versus humming any recognizable tracks. That isn't to say it's just a wash of ambient cues, not at all. What I mean is Kyd manages to convey more than plot and environs, but more to the heart of intentions and circumstances.
If there's anything to be of a “main theme” for “Brotherhood”, it lies in the track “City of Rome”. Rome is where this Assassin's story takes place so a lot of care was taken to have this track anchor everything else.
Notable tracks are of course the sweeping “City of Rome”, the tense action piece “The Brothehood Escapes”, and the solemn “Echoes Of The Roman Ruins”. There is some great percussive rhythms in “Villa Under Attack” which also features a great deal of male chorus stabs. “Fight of the Assassins” is a great duel/face-off track with some powerful percussion, a truly empowering feeling hopefully solidifying in the player's favor.
“Brotherhood” moves so effortlessly between 'beautiful' to 'haunting' to 'down-right scary' to 'lump-in-your-throat' with such care and intention it's just a marvel to behold. Kyd finds flexibility, he finds sensitivity, he creates opportunity and capitalizes on it. If that isn't an assassin's "creed " then I don't know...etc., etc.,
