I think the whole concept behind lyrics is you better mean what you say, or you should like, become a storyteller. I mean, there's a lot of bands who are just storytellers, and then there are bands who actually have something valid to say. And the bands who have valid points are few and far between.

Metallica is a very complicated, fragile thing. On the outside, it's all metal, but on the inside it's very delicate.

I was really, really wild in my early twenties and a bit self-destructive.

Musically, there's a movement called the flatted fifth that's really evil-sounding. It was outlawed by the Catholic Church during the Middle Ages. That movement is what gives you a real evil sound that conjures up dark, fantastic images. It's like an audio horror movie. It personifies what a horror movie is about.

I'm not into that whole Satanic thing. It's just something to fall back on if you don't have much imagination. Singing you fiftieth song about having lunch with Satan--I'm not into it. It's silly.

For the 'Load' album, I was experimenting so much with tone that I had to keep journals on what equipment I was using. For 'Hero of the Day', I know I used a 1958 Les Paul Standard with a Matchless Chieftain, some Boogie amps and a Vox amp - again, they're all blended.
