Roger Ebert called Boston’s Alloy Orchestra “the best in the world at accompanying silent films.” This internationally known trio—Terry Donahue, Roger Miller (Mission of Burma), Ken Winokur—perform their signature score for Fritz Lang’s 1927 sci-fi spectacle Metropolis September 28 at 8:00PM. Alloy Orchestra will also accompany two silent movie classics starring Lon Chaney, THE PHANTOM OF THE OPERA and HE WHO GETS SLAPPED, on 9/29.
