Can I point out the irony of headshot using other people's work to show off his own? I know the use of video from a trailer is common these days, but even the music seems pulled and edited from other recordings. Is this not the case? Is "The force awakens rescored" completely a midi mockup with no audio recordings? Because there are some things in there I have only heard in a real score, and would not know how to mock-up (besides using samples of recorded riffs/runs). But I don't claim to be the ultimate mockup pro so this could just be my shortcoming.
Sam, I don't know you, but I would believe your word if you say it is all midi, even without you posting your mockup. It just seems like a lot of work to say "I don't like modern film trailer music or what they did with this trailer". If you have those skills, perhaps you could use them to score film students work for free, or help new filmmakers to "discover" older styles of scoring. It would be a better use of your time.
And you've missed the point of the original trailer music that was there. To add tension to the beginning that leads up to the release: a star wars theme we recognize. But in films and trailers it is good to hold off on that reward, lead up to it. Building the tension is what makes the original version better, even if it's not a "traditional" arrangement. Sorry if this gets OT, I'm just surprised no one has made these points, and some are assuming TFA rescored is a midi mockup. Or perhaps you recorded it all with a real orchestra? Kudos if so.
