I love Black Sabbath. They made an amazing contribution to music today. Almost every band that made it big in the Nineties owed a debt to them.

Most people don't take some things into consideration. When they hear an album, they hear the artist or they hear the lyric or they hear the melody. But they don't really think about the environment in which it was recorded, which is so important. It's that thing that determines what the album sounds like.

When digital technology started becoming the norm, you've got 50, 60, 70 years of recordings on tapes that are just deteriorating. Like, a two-inch reel of recording tape won't last forever. It dissolves. It will disappear.

I'd like to imagine I won't end up in Hell, but I think I've done too much acid and listened to too much death metal to sit on a cloud next to God with angels floating above my head.

Singing into a microphone and learning to play an instrument and learning to do your craft, that's the most important thing for people to do. It's not about being perfect, it's not about sounding absolutely correct, it's not about what goes on in a computer. It's about what goes on in here [your heart] and what goes on in here [your head].

Some people record onto tape, and then they pay for the tape, and download those onto a hard drive. Initially in a Pro Tools program. Other people go straight into digital, and use no tape at all.

People should never be afraid that Foo Fighters are ever going to break up, it's like your grandparents getting divorced - it's not gonna happen.
