If you wanted to chart new territories and head off over the horizon, you had to make sure you weren't overly influenced by what others were doing ... so it didn't matter what other bands were doing ... we did what we were doing.

Let's just say I'm like a ship passing through storms, resting in ports now and then until it's time to continue the journey. I once told a friend, `I'm just looking for an angel with a broken wing - one that couldn't fly away.'

Led Zeppelin didn't get that kind of Beatles screaming. We had a more sort of macho crowd. But I remember once in the early days of The Yardbirds, we were playing on an ice rink, and the stage was mobbed by screaming girls. I had my clothes torn off me. That's a really uncomfortable experience, let me tell you.

You can't overthink the music. Mood and intensity can't be manufactured. The blues isn't about structure; it's what you bring to it. The spontaneity of capturing a specific moment is what drives it.

Every musician wants to do something which will hold up for a long time, and I guess we did it with 'Stairway to Heaven.'

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.

I believe every guitar player inherently has something unique about their playing. They just have to identify what makes them different and develop it.
