Here's another review of Giacchino's score from the Austin premiere, which I linked on my site last night. This isn't a review of the score-only, but from viewing the film. A couple of excerpts:
Michael Giacchino’s score for J.J. Abram’s STAR TREK is a real ear-opening, boldly-going, riveting trichotomy of quality composed music earning it’s placement among the ranks of the upper echelon of STAR TREK scores.
There were three major components to the score that struck my ear upon my initial viewing of the film. The first is the deep underlying emotion running hilt to tip throughout the entire musical presence of the film. Even the bombastic action sequences were emotionally charged. A mere ten minutes into the film, I was reduced to tears and had only the music to blame.
Secondly, Giacchino’s primary TREK theme is cut from the same swath as other well-crafted themes heard throughout the history franchise yet remains remarkably original. It’s a theme for this STAR TREK yet it nestles comfortably among its popular brethren. I found myself humming it all day today remembering its key entrances in the film (there were many, and they are glorious).
