"Robert Plant has a horrible attempt at a wail at the beginning. He doesn’t get anywhere near it, but it’s still awesome. In a way, live stuff is about the mistakes. You don’t want a note-perfect recital of a song, you want a fucked up, exciting, bum notes everywhere, people falling off their stools version of it. And I think Led Zeppelin are brilliant at that kind of stuff. Everything on this is completely real and it sounds like they’re really trying and not quite getting there – and that’s the thrill. That’s what it’s all about. The white knuckle ride. We didn’t sign up for the teacup ride. It’s real life – there’s a human element to it, and you really get that on Led Zeppelin recordings."

"That said, I love the more ancient sides of British culture as well. This reminds of a really broody, Autumnal day years ago – when there was all this low, grey cloud – when I decided I was going to go to the Avebury Stone Circle. When I was first there, it was deserted and perfect. 

A little while later, I heard a break in the quietness –someone else had arrived. Then I heard these big footsteps, and Robert Plant – Robert Plant appeared from behind a stone! It was an absolutely perfect moment.

I was too shy to say anything, of course, but when I was leaving, there he was at the car park, and, argh, his car was next to mine. I got into the driver's seat, I caught his eye, so I wound down the window…and I just couldn't think what to say, so I just grinned and gave him a big thumbs-up! We've met properly since, but whenever I think of Led Zeppelin, I think of him emerging from the mists like a druid.

I also didn't hear this until I was 27, and then I was all, oh, no wonder they're so popular, this is fantastic! Music was tribal to me when I was a teenager. I was a real indie kid who didn't listen to rock at all. Now I listen to it often, and I think of the house where they made this album, the other side of the mountains to where I live, and it really feels like this music comes from this very old, rooted place. And 'The Battle Of Evermore', with Sandy Denny's voice – I love how the whole of the end-of-the-60s British folk moment is caught up in the way she sings. I love the way those traditions connect us to something deeper.

"You have to remember that this came out when I was 10 years old, and my brothers started smoking pot and listening to that all the time. So we lived a lot of our young intense lives with all that cool Led Zeppelin shit playing. But when I hear Led Zeppelin IV, I guess that's where I discovered that idea of a rock group. So for me, Led Zeppelin never really evokes anything other than these dudes playing this bad ass music. Of course, it's impossible to really play like Led Zeppelin. I mean, they're a total fabrication of sounds and moods and little arranging techniques, little quirks. Jimmy Page is a master of that. It's a magical combination of, what, eight songs? When you listen to them altogether, which we do quite often, I don't see how anyone who loves music could listen to that and not think, 'Fuck, that's cool'. Such cool drumming, such cool effects on the guitars. Robert Plant... it's a weird way he sings. People have accepted it now, but it's a weird screech. So high, with so much velocity, he's really singing at the peak of his energy. That is driving the music. You can't take Robert Plant's screeching out of that and get the same effect. It's just what the song is. That song 'Rock N Roll' [sings] "been a long time since I rock 'n rolled"... if you don't sing it like that, it doesn't have the same effect. He screams that shit with that freaky echo on his voice, it's like some truth from beyond. It's fucking amazing. It's still amazing."
