I owe everything to Nirvana. But I can't let that overshadow the future. For the first few years, I didn't even want to talk about Nirvana. Partly because it was just painful to talk about losing Kurt but also because I wanted the Foo Fighters to mean something.

Someone curating songs for you through your computer or being able to hold 10,000 songs on your watch - that convenience is pretty incredible, but so is the emotional impact of holding a Beatles record in your hand and listening to Let It Be.

I was at a New Year's Eve party, and someone asked me how was my year, and I said, 'I honestly think 2011 was the best year of my entire life,' and I actually meant it.

Develop that individuality by working as hard as you can at what you love.

Different boards do different things to the sound that's coming through them. An old Neve desk does embellish it in a way that makes it sound sort of bigger or warmer. It doesn't change the performance but it does enhance the way that it sounds.

There's a reason why the Foo Fighters don't blast out Nirvana songs every night: because we have a lot of respect for them. You know, that's hallowed ground. We have to be careful. We have to tread lightly. We have talked about it before, but the opportunity hasn't really come up, or it just hasn't felt right.

When you have kids, you see life through different eyes. You feel love more deeply and are maybe a little more compassionate. It's inevitable that that would make its way into your songwriting.
