I think that's one of the fun things about classical music - no one can know everything about it. As ignorant as you may or may not think you are, what you and I know are drops in the ocean in 500 years of music. I love that. I'm listening to the first link now. Diggin' it. thanks for the share.
Mark Isham is a crazy-ass scientologist but he's got some real skill. Thomas Newman I know less about, but more people know him for this thing than for less than zero: By the way, were you aware that in Europe, Legend didn't have a Jerry Goldsmith score it had a Tangerine Dream score? Changes the hell out of the movie.
I did know about the Tangerine Dream score. I think that as a standalone piece, the Jerry Goldsmith score is better, but in-movie, the Tangerine Dream score is a little less intrusive. It definitely has a creepier vibe, though. The Goblins in particular come off a lot more darkly comedic.
