A trend in journalism is generally defined by three or more happenings in the same field. So when I discovered that James Newton Howard (The Hunger Games) had written a cello concerto, Danny Elfman (Alice in Wonderland) a violin concerto and George S. Clinton (the Austin Powers movies) another violin concerto, I thought “here’s a trend” and decided to write a story. In fact, I discovered at least half a dozen concert works by composers generally known for their film music are getting premieres in the next six months — and that more than a half-dozen others had debuted in the past year, with still more on the way. It’s not just John Williams, it’s Michael Giacchino and John Powell and Bruce Broughton and Jeff Beal and many others. Here is that story for Variety.
