"His music, the Clint Eastwood connection... outlaws! All of it, in some way or another, contributes to the spirit of Metallica. You can go down the history from where and how they began to where it’s gone, and to me Ennio’s music has that connection to Metallica. The outlaw element; it’s dangerous but it’s cool. And that was his music – dangerous but very, very cool. With so many beautiful layers.
"I believe a lot of Metallica’s music is built on layers and chance and taking risks. The compositions of layered guitars; the dynamic of that ingredient is really, really cool and that’s the same thing with classical music. Ennio did it incredibly well and he’s a genius at that. I know Orion is a Metallica piece, but to me it has the beauty of an Ennio Morricone composition – the layers and the journey it takes you on, the highs and the lows."
