On Staturday, March 5, students in the Art & Motion class attended a very cool concert at the Somerville Theatre in Davis Square, Somerville. The Alloy Orchestra performed their new score on stage to the newly restored “Metropolis” which is a classic film by German director Fritz Lang. At times, it was hard to believe only three musician were making all those sounds. The musical score was synchronized perfectly with the narrative making the event a totally visceral experience. The musicians are Roger Miller, synthesizer, Terry Donahue, percussion and accordion, and Ken Winokur, percussion and clarinet.
