This "Complete Recordings" version of the score to Assassins Creed Revelations is absolutely brilliant. Series composer Jesper Kyd returns once again, accompanied by Lorne Balfe who works very closely with Hans Zimmer. I read that Kyd scored the gameplay parts of the score, and Balfe scored the cut scenes. I haven't played the game yet, so I don't know whether this is true, but I do know that on album, their two styles fuse together exceptionally well.
The main theme introduced in the first track "Assassins Creed Theme" is a wonderful melody and is reprised several times across the album, although it is used relatively sparingly. I won't go into a track by track analysis because of the duration of the album - it runs for just over two and a half hours, and that's pretty unprecedented as far as game score releases go. It is labeled as "The Complete Recordings", but a little bit of reading online suggests that a few cues were left out. That didn't matter to me in the slightest though - there are 80 tracks in this MP3 album and I doubt many people could find fault with that.
There are many styles of music present, ranging from all out action, to wonderful ethnic sounding tracks, while others are more ambient. I know some reviews that said they preferred the tracks composed by Kyd compared to Balfe. I think this is a tad unfair - Kyd has a unique style that has been present from the initial Assassins Creed game that has continued to the present installment. However, Balfe's contribution (including the wonderful main theme) is also brilliant.
Looking on the production side, I would guess that the majority of the tracks are made up of synths (even the orchestral portions) rather than using an actual orchestra. However, Kyd and Balfe are both highly respected and have a huge range of realistic sounding instruments at their disposal so the lack of a real orchestra isn't a major issue (although I would be lying if I said there were some cues where the string section sounded particularly synthetic). That wasn't the case for the majority of the album though.
All things considered, this is an absolutely fantastic release (and great value for money). The quantity of music present may put some people off - but that said, I would always rather have more than less. If you are a fan of the score in the game, or enjoy game/film scores, this album is really worth buying.
