4. Led Zeppelin, 'Led Zeppelin II' (1969)
I don't really think of [Led Zeppelin] as a heavy-metal band, but they were there at the beginning. They started what became heavy metal, together with Uriah Heep and Black Sabbath and Deep Purple. So they laid the groundwork for what eventually became heavy metal.
I wondered, "What Zep record should I put on there?" Because I love almost all of their records. I love them up till Physical Graffiti. Zeppelin fans are most into those records up until Presence and In Through the Out Door. "Whole Lotta Love," it's like [Black Sabbath's] "Paranoid" – I don't really have to hear it again; I can just kind of close my eyes and listen to it in my head. "What Is and What Should Never Be," beautiful. There's something about that song that makes you just drift away. "Ramble On"; "Moby Dick," even; "Heartbreaker." It's got those classic Zeppelin songs. But it was so difficult for me to pick one [album]. ... My initial gut feeling was to pick Zeppelin IV, because it's got "The Battle of Evermore" and it's got "Going to California," and the softer songs which I absolutely love, but something just makes me go back to Zeppelin II more than the others. At least in the recent year or two, I've been listening more to that record than the others.
Also, Zeppelin III is an underrated record; I think it deserves more credit. If you can call a Zeppelin record underrated, but in the discography, I think it's underrated. Since you asked me to do this [at] this time, I just happened to pick Zeppelin II, and I don't really know why, but it's as magical as the others up to Physical Graffiti.
