The first disc is a reissue of the existing album, released in 1994, beautiful work, twelve pieces reworked in chains adorned with dialogues from the movie. Remastered edition certainly but the original was good. If you have not already, it drives almost single purchase of the trilogy. (Do not confuse with the first Blade Runner album released Version "symphonic" very average.)
The second disc is what is closer to what the diehard fans of the film expecting. We find it almost ten themes taken without amendment, accompanied by two new compounds at the time but not used. This is piped ranges, synthesizer long sheets that relapse into heavy and humid atmosphere of the film. Less varied than the first disc, it is also less alive more than in crowded streets here one wanders through deserted alleys-cons. Two pieces shine with a special brightness: One Alone, and Dr. Tyrell's Death. A notable absence: the disk is short (about 45 minutes) while the major themes of the film (including the introduction) still missing.
The third disc is a great surprise for fans of Vangelis: an original album created to celebrate the anniversary in style at the crossroads of albums The City, Direct, and See You Later, more modern. It plunges into the Blade Runner universe, but perhaps in another city, less black, more optimistic. Samples of the first disc haunt some songs; friends, actors and authors of the film give voice to a global city; Vangelis greet the past but resolutely turned towards the future!
The fan of Vangelis will be understood, the purchase of the cabinet is a pure and simple obligation. The decision is less obvious for fans of the film who do not particularly like Vangelis. As for me, a fan of both, I assign a rating of 4 out of 5, failure of the second disc holding me to the maximum.
