The third and final installment of the American Youth Symphony’s three-year “Goldsmith Project,” saluting the music of Jerry Goldsmith, was in many ways the best yet. The afternoon symposium began with a new 10-minute suite from Under Fire (1983), after which I moderated a panel with frequent Goldsmith collaborators Joe Dante and David Anspaugh plus longtime music editor Kenneth Hall, mixer Bruce Botnick and agent Richard Kraft. Conductor David Newman debuted, for the first time ever in concert, music from Jerry’s Legend (1985) as well as a new 10-minute suite from Poltergeist (1982). Here is a thorough rundown of the Sunday program; the symposium was sponsored by The Film Music Society.
