This story shouldn’t be a surprise. Heavy metal owes a great debt to classical music, particularly the more bombastic efforts around the turn of the century. There’s a reason the Trans-Siberian Orchestra, purveyors of a “heavy” orchestral Christmas-radio staple, draws some of its personnel from turgid metal band Savatage.
One day, I’m going to make a Spotify playlist of rock music for classical fans to enjoy. Get ready for a good dose of Knights of Cydonia.
