You can't just find yourself doing something and not happy doing it.

I bet you can't play slide piano.

I can tell how far I ought to be going, I know how to get there, all I've got to do is keep playing.

I really wasn't needed... Just straightening up riffs, that's all. Just two guitarists doing it instead of one.

I know what I want to get down and I haven't got much time to do it in.

There is no way I would play guitar like a tour de force like I did in Led Zeppelin. John Bonham, phenomenal drummer, young man with his technique, but do you think he would ever have the opportunity to play like that in another band? Of course he hadn't.

There's a very old recording maxim that goes, 'Distance makes depth.' I've used that a hell of a lot-whether it's tracking guitars or the whole band. People are used to close-miking amps, but I'd have a mic out around the back, as well, and then balance the two. Also, you shouldn't have to use EQ in the studio if the instruments sound right. You should be able to get the right tones simply with the science of microphone placement.
