My favorite score is The Journey of Natty Gann. For me this is one of the most beautiful scores ever written (for a very underrated picture). The CD (signed by Mr. Horner) is one of my most cherished possessions.
Following closely are Krull, Glory and The Mark of Zorro.
I listened to the LLL release of KRULL again on the drive to work and back today, and when I got home Holly and I both acknowledged that it's our favorite of Horner's magnificent body of work. The themes are catchy and invigorating and the orchestration dense at times yet meticulous, every instrument clearly fulfilling its role in the musical dialogue without any superfluous filler. It has more majestic power and emotional gusto than most other film scores combined (!), and yes, I'm still proudly rocking the custom made bumper sticker that I had printed up a few years ago in the Maestro's honor:
Krull, aside from the music itself it has a C&C album structure that i enjoy a lot - heroics and turmoil at the start, then mellows out with the sublime weightlessness of 'walk to the seer's cave', into the long foreboding 'swamp' and 'widow' middle, then back to turmoil and heroics for the end.
it used to be The Name of the Rose, when I was in my electronica phase and I preferred my scores uncluttered and serene.
and before that Aliens, back when i walked around with a look of permanent 'wow' on my face, and tried to shoehorn that movie into every conversation i had.
It was one of those moments when film music stepped away from our merry band of fans, and into the culture. All the talk of the young girls going back to the film repeatedly for Leo... no, they went back for Horner, whether they knew it or not. He was the heart and soul of that film.
