Robert Plant recalled a recent meeting with Bob Dylan. The Led Zeppelin frontman told Classic Rock magazine, "I recently did a gig in Roskilde, Denmark, and Bob Dylan wanted to talk to me about touring. So I met him where all the buses are parked, at this big festival, and we eyeballed each other and smiled in the darkness. It was pissing with rain, two hooded creatures in a blacked-out car park, and I said to him: 'Hey, man, you never stop!' He looked at me, smiled and said: 'What's to stop for?' But I couldn't ask him about his songs, because as much as I've been affected by his work you can't talk about it. My work is not anywhere near as profound in what it's trying to do. At the same time, you can get to know the motive and circumstances behind a particular song, without it being 'Masters Of War.'"

Coming on February 20th is Plant's new Digging Deep box set. The limited edition vinyl collection features 16 solo hits and B-sides on seven-inch singles. The eight-disc set is released in connection with the second season of Plant's podcast, Digging Deep with Robert Plant.

Plant was asked about whether the podcast might start featuring some unreleased material: "I've also got forty-plus tracks that I've never put out. I've got stuff that I did in New Orleans with the Li'l Band O' Gold and Allen Toussaint. I've done so many things. I've got a whole album, Band Of Joy II, that I did with Buddy Miller and Patty Griffin. I've got stuff everywhere. So it might be a good way to gather some pretty powerful stuff and just eke it out there. I've just been tidying up my little studio here, to do some rehearsing later in the week, and found some stuff with the Space Shifters that we did at Rockfield two years ago. So it's not just about stuff that came out through the normal channels."

Plant touched upon the fact that he's gone to great lengths to avoid being "that Led Zep parody guy": "No matter what happens, I have no choice. There have been great variants of another me, but whenever I read a newspaper it seems I'm still in Led Zep. I think the problem is that nobody can hear what artists who stick around are able to put out now. If you don't go out and find it by your own volition, it's not going to come down the normal channels. And I think a lot of people who go to gigs don't even listen to the radio."

Robert Plant explained that Led Zeppelin constantly stayed ahead of the curve by never resting on their creative laurels: "You have to be creative and imaginative and move on. And I think the great essence of Led Zeppelin is the creativity and the imagination that developed with each project. And a project is a project. It's not just going back and visiting the past. It's moving forward."
