Led Zeppelin – Led Zeppelin IV
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.
