I was just watching this movie and admiring the score the other day (of course, that's not a rare occurrence - this score is always at least in the back of my head), and wondering when in the world we'd get a release of it.
Hopefully we'll get it in CD format later... but in the meantime I'm just glad we'll finally have all those great cues. The Main Titles when we get our first look at the Turtles in the sewer, the circus-like theme for the battle with the Foot in April's apartment, the tear-jerking, atmospheric cue when the Turtles have their vision of Splinter at the campfire, the "It's Time To Go Back" bridge when they return to New York, and the movie version of the Shredder battle ("This guy knows where Splinter is!")... it's going to be amazing.
One of the cues I was most looking forward to on this album was the "Time To Go Back" bridge. It's basically a revisiting of a cue from a few minutes earlier in the film, when the Turtles are training on the farm, but with louder percussion and without the synthesized koto (or whatever traditional Japanese instrument that's supposed to be, I'm not as well-versed in this as I should be).
But what's heard on the vinyl release is different from what's in the movie. The percussion is comparatively muted and for some reason, the Japanese instrument is present when it shouldn't be. It sounds more like they just took the training cue and changed the pitch and edited it. I'm dying to know what happened here.
Pure utter speculation, but perhaps what you are hearing is how the cue was originally recorded for the film. The version is the film may have used the take without percussion overlays and moved the overlays as the editor thought worked.
