I don't want to scream 'Immigrant Song' every night for the rest of my life, and I'm not sure I could.

Led Zeppelin was a very sensitive and beautiful animal beast.

Possibly the whole creative whirlwind of any musician's life is based on garnering and developing and absorbing more and more experience.

There's so many parts of your life, you know? People say that you don't get any better after the age of about forty or something like that, as a performer. I find all that to be a misconception. I don't feel bad about the way I present stuff. The calendar and the mirror - they're bastards.

I love the feeling of letting fly, of pushing as far as I could go with my voice. The only way you can really graduate how you do it is by doing it regularly to people who don't have to be super impressed. You can do it in the studio all day long but you don't get the flashback that you get onstage.

The past is a stepping stone, not a millstone.
