If you're an American kid, you can't help but be influenced by Led Zeppelin, Black Sabbath and the Rolling Stones because they're always on the radio.

I love Led Zeppelin and Black Sabbath and Guns N' Roses and AC/DC.

I am a child of the '70s, so I love classic rock - Bob Dylan, The Rolling Stones, Led Zeppelin, Van Morrison, and I also love Coldplay.

In between 15 and 20 - probably at around 17 - my interests switched from hard rock to punk rock. And then by 20 they were circling out of punk rock back into Black Sabbath, Led Zeppelin, the stuff that I didn't get to when I was younger.

We're trying to have the band create something beautiful that hopefully one day, 20 years from now, can be picked up by a kid and hopefully have the same effect that Neil Young had on me, or Led Zeppelin or Black Sabbath.

I really don't listen to Led Zeppelin that much.
