I bought it on the 4th may, just before the film was released, BUT..
I didnt listen to it until i saw the movie. Obviously, i heard the clips that were online earlier.
I like how Giacchino had his OWN Trek theme, much like the past composers; Horner, Goldsmith, Rosenman, Edelman, McCarthy. He incorporated his own theme throughout the movie, making a great debut in the track 'Star Trek' and intertwined throughout.
I also like how we heard a tiny bit of the twinkle theme when we see Kirk and Spock beam onto the Enterprise together for the first time. As if he is showing us the iconic moment where the icons beam together for the first time and incorporates a tiny weeny little bit of courages theme opener as if to say "Here they are, Kirk and Spock"
It makes an appearence as the two materialize on the pad.
It makes its appearence right at the end of 'Nero Death Experience' http://www.youtube.com/watch?v=n1mlc-qyLt0
Thats the part i loved, Courage didnt just do the much parodied twinkle in monotone sound, each one twinkled three times, getting quieter. Fantastic, the sound even had the TOS feeling.
The end credits however, is his crowning moment. Not only in the track leading into it 'To Boldly go...' does he put the twinkling and the fanfare, he almost reproduces the sound of the Courage original.
The end credits even have a TOS esque subtle choir in the backgorund, not over powering the orchestral aspect. Fantastic. The iconic choir/female voice is there, but not too much. He also, as said, puts his own Trek theme throughout the end credits, as if his and TOS theme are playing off against each other. and its blended geniusly, if thats even a word.
Enterprising Young Men is by far one of the best tracks. It incorporates Gicchinos theme really well, and establishes it as his Trek theme, only to be outdone in the end credits.
Giacchinos theme sounds epic on head phones, its so huge sounding. It has chimes, trumpets, bells, bass and above all, an epic sounding. Its also a very traditional sounding theme, done in the way Roddenberry actually wanted the TOS theme to go, a more of a space march than a sci-fi sounding theme. I also loive the fact that he used his Trek theme in the opening instead of shoehoring thte TOS theme in. I respect him for that, he has respect to say "Fuck it, its my theme, its opening the movie with the delta and the title card."
