I walked into a scoring session for Frozen, not really knowing what to expect (except that I knew Chris Beck’s score would be great, and it was). What I found was a surprising group of musicians, songwriters, Disney animators and executives who hoped that, somehow, this long-in-gestation version of “The Snow Queen” would somehow resonate with moviegoers. (Boy, did it.) We were proud to introduce the musical ideas first, in the pages of Variety.
