Last night, the Alloy Orchestra performed their original score to the 1927 silent film Chang: A Drama of the Wilderness on Chapels Field. The orchestra, a three-man band of electronic musicians who incorporate "found percussion" into their act, have written scores for a number of silent films, including their 1991 score for Fritz Lang's 1927 silent sci-fi flick Metropolis.At Brandeis, the performance was accompanied by a screening of Chang on a 30-foot inflatable screen. The Brandeis performance was part of the band's fall tour, which will continue through mid-November as the band performs a variety of scores along with silent movie screenings in museums and at universities and film festivals both in the Northeast and across the United States.
