I was asked awhile back what I thought was the best piece of musical score I'd ever heard on anything I'd had done. The answer was immediate and easy. The absolute best score to anything I've ever done (caveated with a "yet", because I hope I work with him again someday!) was Bear McCreary's amazing work on the season finale of Battlestar Galactica season three. No, not "All Along The Watchtower" (which was amazing nevertheless), but the piece just before it. On the CD, Bear calls this track "Getting The Call", and if you remember the episode, it's when Tigh, the Chief, Tory and Sam are all gathering to confess that they've just realized they're all Cylons. I still get a chill when I hear the propulsive, chugging, building theme that brings them into the room. The score is absolutely perfect...
Well, Bear's just put out his score for "The Plan" and "Razor", so you should order those and all the rest of his (brilliant) work, but I'd just like to doff my rhetorical chapeau once more re: his season three piece. It's as good as this sort of thing gets...
