You can listen to Michael Giacchino’s Star Wars: Rogue One score on the Disney Awards consideration site Waltdisneystudioawards.com. There are some minor differences between this version of the recordings and what we heard on screen for the end credits (which doesn’t have the John Williams stuff included).
On the bottom of the page you’ll see a player like this in which you can listen:
Right now, I’m really enjoying Giacchino’s work on Rogue One. I felt it was very different from John Williams while still having a reverence for it. A lot of the music has an “Across the Stars” vibe to it at certain moments, which I dig.
Thanks to Mark Seyb for the heads-up!
