The music is by Dan Gross, one of my former Film Scoring students. One day in The Language of Film, the sound wasn't working on the videotape of The Great Train Robbery. I asked if anyone wanted to try to accompany the film on the piano (every Berklee classroom has a piano, you know), and Dan stepped up. At that moment, he discovered something he really enjoyed, and is extremely good at, and went on to accompany silent films live at the Harvard Film Archive and in Los Angeles. You'll hear what I mean about his affinity for interpreting the visual story in his music, in his touch on the piano keys, in the piece he wrote and performed for the film.
